Where do you meet guys for good sex?

I'm single and not looking for a relationship anytime soon.

But I miss having great sex! My last two boyfriends were honestly not good at it.

I had a FWB kinda thing 7 years ago and he'd make me orgasm 8 times every time! He was super attentive and it made me want to do the same to him!

I can seem to find a guy similar to that. They just wanna get their dick wet and don't care really if I enjoy it.

Where do I go to find a good sex partner?

Oh, and I can't have sex with a guy if I don't trust him. I've had guys continue even though it was hurting me and I don't ever want that again. So, can't do random hookups. Problematic, I know.

I'm also willing to try it with girls cuz I'm pretty damn sure I'm bi but never got the chance to try sex with a girl. But that's even more out of my range of knowledge! How do I meet a girl!? XD

Any advice would help, please and thank you!
