Just a couple hours ago, I was talking to my boyfriend over msn and he brought something up that concerned me. He asked about past partners and if everything was "safe" in regards to protection. He's well aware that I recently had a very sexual affair with a guy, but he doesn't know that we had unprotected sex. It got me all worried because I don't know what made him bring it up, and maybe he's experiencing abnormalities, or getting weird symptoms, but he wouldn't tell me why he brought it up. He just wanted to get it over with because he thought we "missed a step" in the sex part of the relationship. I guess I'm worried because of the unprotected sex, and the STI's and stuff, but I feel fine. I don't have any symptoms, and it's been months since I last slept with the other guy (before I met my boyfriend). But I realize that some people don't experience symptoms at all if they have a STI. I haven't been checked in a while, and since this got brought up, I want to go get checked up this week, but I can't seem to sleep. Do you guys think I should be worried? I'm seeing him tomorrow morning, but I just need peace of mind until then.
