Beginner With More Experienced Partner: HELP!

I 20F have a 30M partner, and he’s VERY experienced it’s almost embarrassing with how little experience I have.

I was also SA’d by two previous men I’ve met, so I’m working on some anxiety surrounding sex. My current partner is very supportive, and suggested I post here to talk to some others with similar experiences/more experienced than him.

I’m going to therapy, and researching a lot on the following topics specifically I want to be confident and comfortable in:

- Blowjobs

- Anal

I’ve done as much research as possible, but I’m hoping that by posting here I might get better advice. I’ve always been a bit sheltered when it comes to these things (very religious), but I want to be a good partner!

Any advice is helpful, thank you!
