Lesbian Sex Advice?

I’ve been with my girlfriend for a while now and we have sex pretty frequently. Most of the time we have sex it involves me just getting her off with my hand or mouth and then we’re done. The problem is, she has an issue where she doesn’t really feel anything from fingering or penetration. I’m a trans woman, and when we have had penetration sex in the past, she’s gotten no enjoyment from it.

She mentions things that she likes that makes it feel better when I give her head or whatnot, but she herself doesn’t even know what else I can do to make it feel better for her. I want to make her feel better than just a basic orgasm she could give herself and I’ve never been with someone who has the issue she has, any advice is appreciated
