Ballbusting is causing pain to the testicles of the male for enjoyment reasons rather than for self defence reasons. Women enjoy it for the power they feel when they can so easily drop a male to the floor in great agony. They also find it amusing to see them sqirming and groaning while holding their scrotums from such a minor blow. Males seem to enjoy their own vulnerability when it comes to a woman exploiting it. Most men become erect at the thought of a woman controlling them by their testicles. (women always aim for the testicles for self defence which is also a turn on for many)
Her fascination in ballbusting was her interest in the male weakness in his testicles and wanted to experience the feelings of power over a man much stronger than herself. She looked for any reason to kick a man in the balls.

Ballbusting is a sexual fetish, a form of S&M (Sadism and masochism)preformed either solo or between consenting partners that can be either FM (Female + Male) or MM (Male + Male) partners whereas Partner A gets a rush of power by inflicting sexual pain on Partner B while at the same time Partner B greatly enjoys this sexual pain.

The S&M practice of Ballbusting is completely unrelated to any non-consenting sexual assaults/attacks, self-defense or other forced violent sexual acts.

Ballbusting can be perfectly safe when done between consenting mature people in a responsible manner. Great care must be given to make sure that ballbusting is done in a reasonable safe manner between very close trusting partners or friends.

Nevertheless, Medical Doctors have advised against this practice since it can lead to permanent injury, erectile dysfunction and infertility which will require immediate medical attention.

Kicking, kneeing or punching the testicles of a male deliberately.

Women find testicles a welcome vulnerability in an otherwise much stronger assailant in self-defence; the famous kick in the balls is a great equalizer.

Additionally, because testicles, along with the penis, are an observable difference in the sexes and because they are what make a man a man, they are often the target (both mental and real!) of female hate (and revenge!) for making men “the way they are”!

Because of the way that an otherwise powerful male can be reduced to a ‘quivering jelly’ by a well aimed punch, knee or kick (in the latter case even by a slight female in ‘suitable’ footwear), many women, and young adolescent or teenage girls in particular, find it extremely amusing to cause pain to a man in this way. The normal empathy accorded to a fellow human being in pain is absent for the most part because the female does not have similar organs herself and is thus unable to put herself in the place of the victim. The fact that testicles are at the very centre of male sexuality and the sex act and pregnancy itself, seems to add an extra sexual dimension; many women and girls become sexually aroused at both the prospect of causing testicular pain and the actual act of doing so. The idea of male nullification is a strangely arousing subject to many women and girls.

Interestingly, when a mammal is in pain, because of the endorphin release in the body’s attempt to attenuate the pain, the endorphins can produce a sexual high. This endorphin release is greater if the male is aroused sexually as the sex act itself often exposes the testicles to trauma as they impact upon and are trapped and squeezed against the female body. The male must continue despite the pain for the survival of the species, so natural selection has provided for the extra release of endorphins to ensure that the male does continue by counteracting and blocking the pain with pleasure. Women and girls please note, if a man is sexually aroused and self defence is called for, as in a rape or attempted rape, you will have to kick considerably harder than usual to dissuade the man from the attack!

This has led to a by far from modern but increasingly popular phenomenon called “ball-busting”; an activity where women and girls kick men in the testicles for the pleasure of either one or both of the parties involved. In the consenting act of ball-busting the above mentioned endorphin release in the male is sometimes made greater by the psychological effect viz; - that “otherwise caring women have knowingly caused pain to my sex organs for their own pleasure, despite knowing that it could damage me for life”, - ergo the act is a sexual one. In grown women ball-busting, unless it is in revenge or punishment for some wrongdoing, such as infidelity or an act of male chauvinism or sexual harassment, is usually between consenting partners. In young adolescent and teenage girls however, it is often for their own sole pleasure as, because of either a lack of understanding or a lack of care, it is carried out with too much force causing real injury. Kicking unexpectedly from behind or from the side, it is possible with the currently fashionable long and sharp pointed toed shoes and boots to rupture (burst) the fragile epididymis with only a fairly moderate kick; apart from intense agony this, whilst still leaving the male intact as a male, will render that particular testicle impotent. In fact such concentrated energy can be obtained at the tip of the pointed toe of these shoes or boots, that a well aimed kick that traps the testicle against the body or side of the leg, can rupture the actual testicle itself. The testicle will then be unable to repair itself and will ‘die’. It should almost go without saying that a stiletto heel will cause the same effect in a kick to a prone victim; and if used to stand on the victims testicles in the case where the testicles are placed on a table or on the floor (with the victim lying face down), these thin heels will penetrate the scrotum and testicle entirely, - right through to the floor! Again the victim will not only be in considerable and helpless agony (he may die from shock), his testicle will be entirely useless and if both testicles have suffered this fate, he will effectively have been castrated! Without the testosterone produced by his now dead testicles, will no longer be a ‘man’ in the real sense and will start to take on certain female characteristics.

That a direct connection exists between the rapid rise and almost universal adoption of such very long pointed and thin heeled footwear (across all female age groups) on the one hand, and an underlying and partly subliminal female fascination with testicular destruction on the other hand, cannot be entirely discounted!

A similar connection was observed in the late 1990’s between the rapid increase in popularity of “ball-busting” and the platform and chunky heeled square toed shoe and boot craze! Many young women reportedly felt powerful in shoes that seemed to ‘say’ “kick”! However, despite the fact that these bulkier shoes cause an incredible amount of paralysing pain initially, by their large size ensuring that the both testicles and thus more nerve endings are involved in the kick or stomp, it is not usually possible to cause lasting damage so easily. A woman or girl would have to be more determined, such as stomping them on the floor in some sort of mad Spanish dance or kicking them against a warm concrete step.

Ball busting desires in males are not surprisingly connected with both masochism and either shoe/boot and/or foot and leg fetishism. The sexual high created by the female striking the testicles with the fetish object can cause ejaculation that in some cases is prolonged and copious in quantity.

Ball-busting is of course not solely a heterosexual phenomenon, it as might be expected, a homosexual phenomenon also and is at least as popular in homosexual circles as it is in heterosexual ones. It also has its bisexual advocates where normally heterosexual men are involved with either transsexual males or transvestite males; or even males whose only concession to transvestism is the wearing of women’s high-heeled shoes or boots. In this latter case, the kicker uses the shoes or boots to kick the other man in the testicles whilst openly masturbating himself! The juxtaposition that takes place is supposedly that the kicker looking down on the scene and watching the women’s shoe or boot strike the testicles of the other man, becomes in his mind also the kicked man as well as being the kicker, - who is not he, but the fantasy woman of his dreams! The receiver supposedly gets the ball-busting thrill with the added masochistic humiliation and embarrassment that he isn’t supposed to feel sexual pleasure at all because it is being done to him by another man, - and yet he can’t help but feel sexual pleasure because of his addiction to the women’s high heeled fetish objects which are the direct instruments of his sexual pain!
Her ballbusting technique was to alternate kicks to his testicles with the wooden platform of her high-heeled clogs and to rub the tip of his manhood with the rippled rubber sole. She sensed the time had arrived and gave him a hard ballbusting kick straight into both testicles; he cried out and as he ejaculated she continued to kick him feeling her own orgasm rising inside her.

The infliction of pain to a male's testicals, usualy by a female, for pleasure, sexual or otherwise, to one or both parties. Often practiced with consent on masochistic males.

Non-consentual ballbusting is sexual assault and should be reported as such.
