I was experimenting with a friend and we dry humped. We both had our clothes on. He was wearing boxers and pants (jeans/sweatpants) and I was wearing jeans, underwear and a pad because I was on my period. This was my first time experimenting. We had guidelines where he wasn't allowed to come on or around me. I wasn't aroused at all. I was experimenting because I think I am a straight asexual. I like men but I do not like the idea of having sex. He was trying to help me figure out if I really was asexual. The last time we did dry hump I told him to move away to the other side of the bed and not be by me. We had all our clothes on and I wore a pad. He came but far away and not on me at all. I recently got sick today and yesterday. This happened a week or two ago. I'm naturally a worry-wart and I have severe anxiety disorder. I am scared I may be pregnant because I was nauseous those two days. Both my guy and girl friends tell me I'm okay and that I've worried myself into sickness. Somebody please help me?
