Been wit my bf for 9 months. First times we had sex he would cum so quick like 30 seconds. Later on he would pull out and go back in to make it longer. Now in the recent couple of months it seems like he could go on forever and has to use his hand to finish himself off. Does this mean hes not attracted much anymore? He seems to want sex but then always end up like this. We only see other couple times a week.
