<human>: (I stole the "early arrival" from another post,not trying to claim it)
So back story, my boyfriend and I have been dating a while. We are very serious and have talked about marriage in the future. 
There was a lot of sexual tension between us right as we started dating, so the first time we did the dirty, it was..um..fast. ( it seemed to hurt his ego) Our sex life was very active, but I noticed that every time he "arrived early", he would be very distant and not want to have sex for a while.  I have never in any way acted that I was not satisfied (but I clearly did not "finish" in under 2 min).  He has admitted that this is the reason that our sex life is nearly none existent, but does not want to talk about it.  How can I make this better?
