Feeling bad

So I (f20) recently lost my virginity to this guy MUCH older and WAY more experienced, like 40+ body count. He’s really nice and good at pleasing me, but i feel really bad because 1. Him taking my virginity took the span of 3 days for him to fully go inside, just because it hurt so bad, and 2. I’m not skilled at all. I do give him head a lot and recently he told me I was getting better so it kinda clicked to me that I must have been pretty bad at it before, so it made me kind of insecure. And now, when we have sex, he had to finish by jerking off and I just feel so bad because I can’t do have the moves he wants me to, and when I try, I just go slow because im not used to doing them. I kind of realized he likes hard and deep sex, and I let him go hard on me when he’s the one moving his hips, but like if im on top, I cannot go fast for the life of me bc I’m so new to it 😭I hope that makes sense.

Anyway, I was just feeling kinda insecure and just really bad for him because he’s the kind of guy who’s had many threesomes and been with many many girls, and he will tell me some funny stories about his past but it sounds like he’s sometimes reminiscing about those girls and their skills. Hes even asked me if I would do a threesome with another girl since im bisexual, and said how much he would love it, but I told him im not that advanced yet 😅 and that I don’t feel comfortable doing that:(

but i feel so bad that I am willing to do it if it will make him happy. I do try to watch porn and take mental notes and even read comments on reddit about tips and stuff but I just feel so bad and so lame :(

Does anyone have any advice or tips or words of encouragement 🥲
