I (20F) have been sleeping with my partner (23M), my first sexual partner, for over a year now. He has an extensive sexual history and has experimented widely; I did not even touch myself before him. I have learned quickly and become increasingly confident. I am surprised at how quickly things progressed, actually, given my usual reticence and deep-set fears about my unattractiveness. Regardless, our sexual chemistry has only gotten better since, and I love that aspect of our relationship.
I still want to bring him greater pleasure, though. I have this need to be the perfect partner (obviously impossible, at the very least for me), and that includes the perfect sexual partner. He gives me extensive praise and says I offer things previous partners have not (extremely enthusiastic blow-jobs with eye contact, flexibility, dominance and riding him), but I feel like an imposter. I don't think I am good enough at riding him, and I wish I could go down on him better; I wish I could master pompoir techniques and offer him more. I have asked him what more he wants, and he only draws a blank, but surely he has seen, read, heard, experienced better than me, at least in certain aspects. I am anxious about this and unsure of how to properly improve. How can I take our sex to another level, make him feel euphoric?
