sex advice

My boyfriend and i have been together for almost 5 months and we have sex almost every day, but he has never made me orgasm. i can make myself orgasm so easily when i play with myself.. and he is starting to really get upset by it and feels like he’s not enough. when we have sex i really really do feel good and like i could cum, but it’s never gotten to that highest point for some reason, even when we go for hours. any advice to why this might be? any tips or anyone who can relate??
