so my boyfriend came in my mouth and put it back in his pants, then we made out for like 5-8 minutes so it was dry of course and that's when he pulled down my pants and underwear. first he checked if he had any semen and wiped it off just in case and made me clean it with my mouth just in case... anyway he started rubbing his private part onto mine for a bit but then he pulled away and a string was formed and we both panicked. he touched it and said it wasn't sticky so we assumed it was just spit but we still have concerns. also whenever he ejaculates, he goes to the bathroom and usually when he pees some cm comes out but after that we went to the bathroom and nothing came out. can i get pregnant ?
