When a girl gives you a blowjob and she never lets you cum in her mouth. She leaves you unfinished and you get blue balls, a horrible pain.
Man: OH MY FKN GOD! You never finished! Now I have blue balls.

Woman: *laughs*

the excrutiating pain a man receives when his balls swell to the size of coconuts because of lack of sex, unfinished bjs, and just not cummin when he knows he should.

Cure: JUST WACK IT MAN!! or get your woman to help you out and do the job right. It's that simple to make the horrible pain go away.
note to all women,

NEVER NEVER NEVER give your man blue balls...its the worse pain he will ever feel in his life and he never deserves it...well, almost never...

A painful condition when a man has been profoundly sexually stimulated but not allowed to ejaculate, leaving his balls feeling heavy and sore. It is my mission to relieve this unpleasant phenomenon.
His girlfriend had left him with blue balls, so I took pity on him and sucked him off until he came in my mouth. We both felt better after that.

When a guy is driven to extreme sexual arousing without ejaculation.

The effect is a dull pain in the testicles that lasts for at least three hours.

The only cure is to beat one off, but this can also be painful, as it hurts to disturb the area.

The best known method is to simply go to bed and sleep it off.
Sharon rubbed her arse on my cock for ages. She wouldn't shag me, so I went home with blue ball.

arousal of the penis without ejaculation, causing discomfort in the lower abdomen. Similar sensation to being kicked or hit in the tescticles.
She left me with a throbbing boner, man do I hate having blue balls.

Blue balls happens when your with someone, kissing or something, and you are aroused for a long period of time, but you never ejaculate. Your balls may get bigger, or even shrink a little, and there is a slight bluish greyish color sometimes.
The pain is pretty bad. If you walk around, your balls and stomach hurts, but for a long time. It feels like you were kicked in the nuts, like when you get that stomach hurting feeling after being kicked there.
To cure: Have your partner finish you, or (God forbid), you gotta jack off. Without cumming, your balls can hurt for awhile. You gotta be careful not to go to fast because it hurts. IMPORTANT: This is kinda funny, but when you jack off after having blue balls, you will cum SO MUCH!! When I dont got blue balls, I cum like one solid piece, but with bllue balls I shot out like (No kidding), 5 good, solid shots. Be ready. Kinda like a cheap porno.
YOU: After Jenna came over, we kissed for awhile, but she left before we could do it.

FRIEND: Man, that sucks.

YOU: Yeah, and I got a serious case of blue balls.
