I was recently introduced to a guy by a friend of mine to potentially start something. We got along well. He's only 21, so I was a bit hesitant, but open to get to know the guy. Anyway, we went out a couple times got to know each other. He explained he had only been single for a couple months after being in a relationship for 2 years, so he was still not completely over the ex, but open to get to know someone new. Fine. I was cool with that. We went on a couple dates and we ended up having sex. Once with a condom and once without on a different night. I bottomed...which I never do, but Idk why I actually did it, and especially without a condom. I guess you could say I was comfortable with him? Sounds stupid, I know. Before he actually penetrated, we did look at each other like, should we? So I asked...should we? And he replied "I'm only okay if you are. I've only been with my ex and now you" so that closed the deal. It wasn't rough, not long at all and he didn't finish inside me...but now he seemed to have moved on and not really tell me about it. My friend who introduced us told me he's met someone else and hanging out with him. Of course this makes me feel horrible and stupid. I really should have known better. I went to the clinic where I get tested and explained my situation and they told me to wait for this upcoming weekend, which would make it about 3 weeks since my encounter with this guy, but I honestly can't help the thought of something being wrong. I have never put myself in a risky situation like this, because I know how I am. I'm very paranoid when it comes to stds.
