I will admit that I have made the bad decision of going unprotected. It's one of those being young in the heat of the moment kind of things. But then, that doesn't make it any less stupid to do so and I use a condom from now on and require that everyone I'm with uses a condom (or I know them well).
I got tested for insurance purposes, but I haven't heard back from them yet as it's been more than three weeks now. I'm not really sure what to think of that though as I'm pretty sure I would have heard from them if I had any problems. But, now that I think of it, I guess I could always give them a call and see what they say.
We repeatedly hear that we should always use a condom. But some people put up a defense mechanism because we heard it so many times and we associate that to when we were children. But, it's surprising about how many people don't heed the call since they have this invincibility complex about them.
And to comment on invisibleman's posts, I have two stories about something like that. I was on the gay.com forums for a bit while looking for sex, but not desperately. There was one guy that actually was looking for HIV positive men while he was negative. He told me that there's a thrill when taking a risk like that, similar to having sex in public or at your parent's house when they're home. Of course, I said no to that.
Then there was this other guy that was positive and he was looking to get into that thing where someone leaves their door open and allows any guy that wants to come in to have their way with them and leave. His profile said that he was BB (bareback) friendly and I asked him about that. There was another profile that said that he was positive and that is when I told him no. But that wasn't all. He tried to convince me to be with him anyways despite me using a condom. He tried to convince me with statistics of getting struck by lightning before getting HIV while using a condom and that someone who was negative was going to be doing him anyways despite him knowing that he was positive. That disgusted me and was an emphatic no, starting with the BB friendly thing.
So yes, there are crazy people out there that really don't care about themselves or others, as long as they can get some sexual pleasure from their experiences. It really helps to ask before you go and ALWAYS wear a condom. If you don't want a condom, then find someone you can confide in (not necessarily a bf/gf) and gain some trust before you do that. I will admit, I have wanted to see what it feels like to have someone cum in my ass, but my life isn't worth the 20 minutes of fun that might come out of that.
