>>33392785 (OP)Every woman is different. They're a lot more different from each other than you would think. The way to be good at sex is therefore to be good at learning how to please any given woman.
In practice, this means you need to be comfortable asking questions like "do you want me to go faster or stay like this?" or "is there anywhere you like my hands to go?". You can be less explicit; this is going to sound silly, but if she's a moaner then you can use her moans a bit like a metal detector. The more she moans, the more you know you're doing something right. The less she moans, the more you should probably change what you're doing. But never be afraid to just ask questions. So long as you treat it like any other conversation the mood will stay sexy. Just don't make a big deal out of it.
It also means you CANNOT take it as a personal insult if she gently asks you to do something differently. For example, if you're licking her clit and she says "oh, I'm too sensitive there!" then you should, quite logically, stop licking the clit and start licking the part around the clit or kissing her thighs or something. You should NOT double down out of pride and just hope you can bulldoze through her discomfort by showing her how good at licking clits you are. It's not an insult on your pride, it's just good advice. She knows her body best and she doesn't expect you to know these things by mind reading. She just expects you to care about what she has to say about her own body.
This FUCKING simple mindset is what led to one girl calling me the best sex of her life, and that was saying a lot more about the other guys she'd been with than it was about me. You're new to sex so just be ready to learn and don't worry about being imperfect on your first go.
And don't forget that sex is a two way street. It's not some sort of mating ritual where you have to prove to her you're amazing at making her feel good. You're working together to make each other feel great.
