3) Hopefully you will channel you angst into better preparation/prevention in the future (however, nature does not allow for adequate blood flow to the brain and the genitals at the same time)
LMAO... This is so true. Even if you are practically certified OCD (like me), when u get horny enough sometimes fear disappears.
But now seriously... I see the guys here encouraging GC to alleviate his fears, but lets be realistic. HIV maybe statistically difficult to catch, but the figures are rising thus when it comes to such diseases.... complacency can never be an option. People need to stop saying unprotected sex in such a scenario is safe.
I am going to be real as possible, although the likelihood that you are infected is
very low given all that you have said, what happened still carries a strong risk. Penetration does not need ejaculation to cause infection, precum is enough. Although I dont honestly believe you are infected given what your boyfriend has said, your best and only bet is to wait for your 3 month test results. If you are clear there, then there is no need to worry afterwards, forget about it and move on. There is also the 6 and 12 month tests aswell... but as far as I am aware those tests are pointless if you have already been confirmed as HIV- at 3 months, especially given the advances made in diagnosing the disease. However if you are sexually active...then taking regular 6 month tests should become the norm for you.
The next time you mess up like this, go to your local HIV clinic and request something called PEP. Its a treatment (or virtual cure) that is capable of destroying HIV the moment it enters the body. On the downside it has to be administered within 72 hours to work...and its an on going treatment that will totally screw with your immune system for the next 6 months, making you too tired for work, study or anything. BTW my uncle is a GP who taught me all of this stuff .
On a side point...and I hope I dont get flamed or cause offence... but why the pre-ccupation with anal sex amongst gay men? Is penetration absolutely necessary, given the other risks it can cause? Honestly, the human body is not really equipped for that kind of trauma. I am sure oral sex and frottaging (google it)

can be just as pleasurable and is a billion times safer. People need to be more creative when it comes to sex, now ...more than ever.
Anyway...back to my

obsessions...
