Pretty personal but I have to share with you ladies!!!

So my boyfriend and I are wildly attracted to eachother. Our sex life is great minus one thing.... I don't think he's ever lasted more than 5 minutes..... Our foreplay is good and gets us going but once I start getting into the sex he comes. I don't know how much longer I can deal with this...!! It's not enjoyable and it doesn't satisfy me anymore. What should I do??
