How do I get him to climax? 🤔

Ale
My SO and I have been trying new ways to please eachother. I'm pretty new at sex and not being able to please him as easily is frustrating.
So far I can only get him to cum during oral and I've only been able to 3 times since we've been together. 
He's made me orgasm multiple times through oral, fingering and sex but I haven't been as sicceful. 
Any tips? Ideas?
