So i have met this random guy for a hook up.i dont know about his health issue.so we had foreplay involving kissing,licking and sucking each others tools.we proceeded towards sexual intercourse he tried to insert the thing inside my anus but it was so tight it never went completely inside now why i m worried because he was not wearing condom.i cant tell whether it went inside or he had precum during that time .all i know is that he applied lot of oil as lubricant still it didnt go inside.
