Bf doesn't cum from blowjob

Unity

I have been with past guys and been able to successfully give head, sometimes I kinda liked it.

And I still do enjoy making him feel good but he only cums from sex or jacking off. Even during sex most the time he'd ask me to stay still. I'm not really sure how to feel about all this. I've been working on being less and less insecure but when its someone you care about and love. Its harder to be sure of yourself.

I would appreciate any advice on this, thank you!
