Inexperienced.

So the guy I'm seeing only just lost his virginity last year at age 24 and he doesn't watch porn it's never been an interest of his and I really enjoy having sex with him it feels great but his last gf could orgasm from penetration only so when we have sex and I don't orgasm he gets disappointed I've tried explaining to him I need more than that and that actually most women can't orgasm from penetration alone but I have no clue how to tell him what I want and how to touch me my ex had a fondness for going down on me so that's what he did but this guy has no clue where to start or what to do. Any advice would be appreciated sorry for the long post.
