Is he bad??

Ok so my boyfriend and I have had sex lately (5-6 times) we were both each other's first and that was basically the first time I've seen a dick. When we have sex I don't/can't cum. I don't even really feel it tbvh. It feels good going in and out but fingering is better. He enjoys it and cums. We have tried a few different posistions, your average on top, underneath, doggy etc. but I still don't cum. What are some tips and tricks so that I can enjoy it as much as he does. Because there is tension now because he feels like he isn't doing it well enough and I feel bad
