Hello,  Me and my friend had a small sexual run in last Friday night...before we did anything, I urinated and it started with her giving me brief oral sex for around 3-5 minutes then she tried to get me to insert my penis inside her from behind...but I could never get it in at all according to her. After around a minute of not being able to the only part of me that did go in her was my finger and I ended up pulling my penis from between her buttchecks and finishing on her butt and quickly wiped it up...after all that I panicked and went to CVS and got her plan B and she took it. She told me that I was never inside of her just close to her vagina...but I was so scared I wasnt thinking... Could she be pregnant? She said that I wasn't in her at all and that the only part that was in her was my finger she said no chance precum could have gotten in her either and that the most that happened is that the tip of my penis barely grazed her vagina lips but never went in at all...im just terrified. Also she has irregular periods so it's hard to know if she was ovulating at the time or not...which only adds to this stress
