Sex question

So basically my bf has a lot have experience with sex and I don’t. Everytime we have he cums and everything, but we never talk anout it. I’m worried that its not like mind blowingly good for him. I’m also bad at blowjobs, so it’s like idk. i feel a little discouraged. Also lately he hasn’t been sexting me. I’m worried he’s not that turned on by me anymore and that sexual fire has burnt out. anyone have advice?
