Okay, first of all, you can't get AIDS from touching any one's blood. You only get it from having the blood of someone infected with AIDS enter your system somehow. The same is true for semen and breast milk.
I know it sounds retarded, but there actually are people who don't know this, like AIDS just magically generates when blood touches the air or something, like this one time when I was fifteen and I broke this kid's nose in a fight that he and his friends instigated and he wiped his blood on me and said, "I hope you gets AIDS." True story, the kid was a fucking dumbass.
Second, AIDS was not invented by the government for "population control," you fucking clod, and no, they aren't keeping a secret cure from the public. Just because they said it on Chappelle's Show, that doesn't make it true.
The most widely accepted theory of the origin of AIDS is that somebody fucked an ape or a monkey, then spread it to other humans. This may sound weird to you, but trust me, bestiality is far more common than you can possibly imagine.
Third, AIDS does not only infect gay men. Straight people, man or woman, can get it too, through any kind of sex, not just anal. It can be transmitted through oral sex, vaginal sex, or any other kind of sex. And just because you don't cum, that doesn't mean your safe.
You cannot get AIDS from a toilet seat.
You cannot gets AIDS from sharing food with someone.
You cannot get AIDS from skin contact.
You cannot get AIDS from having someone sneeze or cough on you.
You cannot get AIDS from mosquitoes.
You cannot get AIDS from urine or saliva.
You get AIDS primarily from fucking infected people. This doesn't mean that you will get AIDS from fucking just anyone; only from infected people.
Prostitutes are likely to have AIDS, regardless of gender, and if you fuck one, you're taking a serious risk.
There are no cures for AIDS, and there are no vaccinations for AIDS, secret or otherwise. Once you get it, you're fucked. No one is immune to AIDS, straight or gay, man or woman.
In most of the Western World, you are extremely unlikely to get AIDS unless you are A) completely fucking retarded, or B) raped.
