Hi, I m someone with very high anxiety, and I did myself no favors last night. It had been a bit for me, and more than anything I was curious about the whole casual sex thing, and wondering if I was missing out (NO!) I had my first (and only!) one night stand last night with a girl I didn t know. I used protection and well before climaxing I pulled out and she gave me oral. Genital to genital was probably only about 5mins. I know she is promiscuous, which is what scares me the most. And probably also just not knowing her. At the same time, I know she is careful as far as protection and assured me she gets tested regularly. I did notice a couple of red marks in her inner thighs. She is a heavier girl, and told me those were chafe marks. Of course I ve been freaking out tons. I should have known I would. For the most part reading other peoples stories online is freaking me out more. If I could find something to worry about it would probably be herpes. I wish I could know NOW, but I see that I would have to wait at least 4 or so weeks for the test to show anything (if I did contract anything). Any thoughts? Already not sleeping or holding food in
