I don’t sexually satisfy my gf

I am very inexperienced with women in general because I had a really late glow up. I went from having no women interested in me at all to having a bunch of attractive girls into me in a very short amount of time because of late puberty.

Because of this, I don’t really know that much about sex and intimacy. It’s really embarrassing but I didn’t know that kissing a lot and setting the mood with lots of foreplay was a thing before sex because no one had ever shown me that before I met my gf, as I’ve only had sex like 8 times ever.

I overheard her talking about how the buildup and foreplay with a guy from her past was 10/10 because the buildup and tension was insane apparently.

It made me feel really insecure because I don’t really know what that stuff means and I feel like I’m never going to live up to that other guy. I have been initiating sex way less because I don’t know how to give her 10/10 foreplay, and I just freeze up and get in my head.

Since I started getting more hesitant, she has told me that it is a massive turnoff that I am afraid to initiate sex with her, and that I am not being dominant enough during foreplay. The thing is, I am a confident person outside of sex and I am dominant during the actual act, but I feel like my lack of knowing what to do makes it hard to be dominant.

The other day we started kissing and she stopped me, asked me what I was doing, why I was kissing her with such little passion, then she got up and left my house.

I have been told in my limited experience that I am really good at oral and fingering and I always go down on her and try to focus on her pleasure, but I’ve never even had make out sessions or anything like that before her, and these interactions with my gf are making me feel like I’m horrible in bed and make me feel really inadequate. I’ve tried to communicate this with her but she gets really frustrated.
