When i first started having sex with my ex girlfriend I would come really quickly.. She was a virgin.. I was so close to a virgin it wasnt funny (had sex, on night stand.. but that lasted about 2 minutes before we got walked in on..) I would come really quickly.. I think that most of it was mental.. as time went on, it got better but every now and again i will still come really fast. When I was with my ex I would used a jell called detain.. It numbed you for about 5 minutes then it wore off.. It help get through the minute man phase. Mostly do to sexual inexperience.
