Need help!!

So my boyfriend and I have been together for over a year. We are very much in love and very faithful to eachother. We began having sex after about 3 months of being together. I was his first girlfriend so he was a virgin, im not. We keep having the issue where he cums pretty quickly, like 4-5 minutes into it and he's done. And i havent even begun. He's Googled things and tried them and they haven't worked. So I guess I'm asking if there's anything out there that could help him/me out??? Any tips tricks or advice would be appreciated!!
