I am 21 years old, and have a two year old daughter so am obviously no stranger to sex. My new boyfriend, however, is a 22 year old complete virgin. We have tried to have sex on multiple occasions but once we really get ready to go for the gusto he goes limp. All the rest of the time he is extremely erect. He and I both can't understand why he continually can't stay hard even though we have tried every position and possibility in the book. I think it has something to do with the fact that he and I are both Christians, but I think his conviction about having sex before marriage is so heavy it wont allow him to stay hard. Please help!!! It's getting to the point where he wants to try almost every night and I am so tired of trying.
