Man, you've been programmed by the sexual guilt propaganda!
People can and do get STDs, obviously the risk is real. However, I'm hearing from a lot of guys these days that think every sex act is likely to result in some kind of disfiguration or death.
Banging chicks with a condom on is not a high risk factor for disease, you should really speak to your Doctor about the risks. While the safety net is not 100% effective, neither is riding in a car with your seat belt. Perhaps, we should all go back to horse riding, but alas we might get kicked in the nutts by the horse then.
The odds of you having HIV from having protected sex is nearly nil, incredibly unlikely. You only need to get tested if it's for your own comfort. Protected sex is not considered a high risk factor for HIV. HIV, although can be contracted by anyone at any time during risk behaviors, is not particularly easy to aquire. From
NY Times
"The researchers, Dr. Isabelle de Vincenzi and her colleagues at the European Study Group on Heterosexual Transmission of H.I.V., also found that patients who have already been made ill by the disease are more likely to transmit it to their partners.
Dr. de Vincenzi is based at the St. Maurice National Hospital in France. Her study group includes 10 medical centers in eight countries.
The researchers tracked the cases of 256 men and women whose partners were infected with H.I.V. They found that only 48 percent consistently used condoms. Among the couples who did, there were no new H.I.V. infections.
For the 121 couples who did not regularly use condoms, 12 of the uninfected partners contracted H.I.V. within four years. This led the team to calculate that the risk of infection from unprotected sex was about 5 percent a year. "
There's real data for you man. While everyone has heard some story of "this one person" who got HIV from a single, protected encounter, that 1) May not even have been the entire truth 2) Is definitely not the norm. Just take a look at those data, even regularly banging someone with HIV, as long as condoms are used, typically does not result in HIV infection. I'd be more worried about herpes or bacterial infections than HIV.
Personally, I had an HIV test done at around 50 lays, many unprotected, and came up negative. I just had a gonoreah and claymedia test done, both came back negative after some symptoms that turned out to be nothing related (although I took the meds for claymedia anyway based on a docs recommendation since they were so cheap).
