Talked with gf about sex, turns out she doesn't really care for what I do to her.

Me and my girlfriend of four months have been having a lot of sex. But after her failing to orgasm in the last three times I'm getting worried that she hasn't actually orgasmed at all with me.

I've always eaten her out and fingered her with various guides I've found online. I keep feeling some contractions but she told me she didn't finish.

I tried asking her what she likes and what feels good to her but she goes quiet when it's about her probably because she's not fully comfortable telling me and she doesn't really know. (And then when she goes down on me she's happy and talkative again)

It turns out most of the sexual acts I was doing for her weren't really doing much, fingering was the best thing aside from penetration, but I don't trust that, I want to give her a clitoral orgasm.

This kind of tore through my ego and my masculinity, I completely thought she was enjoying it which is what turned me on for the majority of our sessions. I want to talk with her about it but she's not talking back.

Talking about things actually made me feel worse and I feel like this confidence fall is going to hurt me. Do you have any tips to make it easier to her to cum?

I just can't let myself rest until I make her orgasm.
