My boyfriend can’t cum? PLEASE HELP

My boyfriend & I have been together for only a little over a month but we’re very in love (I know it’s early don’t judge, that’s a different topic 😂). He eats me out SO GOOD he literally makes me cum every time & no man has ever done that to me before. It’s amazing!

I’m his first real girlfriend and the first one to do things with him. I’ll give him a blowjob/handjob for like 20 minutes and he won’t cum! Then I’ll get too tired/discouraged to finish :( I’m so stressed about it because it’s never happened to me before.

My last boyfriend didn’t cum the first time we had sex because he was nervous. I thought that was the case at first but we’ve done it like 10 times and he still hasn’t came.

He tells me that it feels amazing and that he’s insanely attracted to me. His dick is literally hard like all the time we’re together.

Why can’t he cum for me? Has anyone else ever experienced something like this? Does anyone have any tips or something else I can try? I just want to make him feel as good as he makes me feel :(
