Sometimes my bf can’t cum whenever we have sex. Usually we just take a break and then the next time we go again he will cum.

I’m getting so discouraged. I’ve never gotten my bf to cum from a handjob or a blowjob (he says a girl has never gotten him to cum from either of those things) and sometimes it takes him longer to cum during sex. I feel like I’m totally failing to pleasure him😭 I’m getting frustrated and discouraged and honestly embarrassed to the point where i try to avoid sexual things and I don’t want it to be that way.

Please help me? Any advice would be great. I’ve tried watching porn to learn things, and ive asked him what I need to do differently and he always says everything I do feels great, he thinks he’s the problem. TIA😔
