My guy friend and I have been talking for a few weeks now and we've been open about everything, I've told my embarrassing stories and what not. Well today he said he has to go to the doctor and I'm a very open person and I tend to get up in everyone's business but he said he didn't want to tell me and now I'm questioning what could be his problem, I'm just concerned and would like to know something, not even in detail but we were going to hang out and now he hasn't mentioned hanging out in the last few days. He went on vacation with his buddies and I'm wondering if he didn't mess around because we are not official yet. Does he have and STD or and STI. If so was he going to tell me before we had sex. I'm not trying to invade his privacy but it could effect me in the future. What do you all think?
