Relationship advice

Hey guys! I need some insight from my fellow females about an issue I'm having in my relationship.

We've only been officially dating for about 10 months, and usually I have a pretty high sex drive. I remember the last boyfriend I dated, I'd make him pull over five minutes away from the house so we could fuck. But my boyfriend now, I fucking love him and he is my best friend, but I have only orgasmed with him twice. I've come close before but never finished. I can orgasm within 5 minutes of masturbating but can't orgasm within our 30 or so minutes of intercourse.

I'm trying to teach him to do more foreplay and to use techniques I like so we can both have a happy ending, but I'm having trouble communicating with him. I don't want him to think he is doing anything wrong, but I don't want to always have to masturbate after sex just so I can orgasm.

Help!!
