Now you got lots of important medical advice that I think you should listen to. Also, you should really try to masterbate to see what you like. Try to focus on your clitoris and what's external that gets you turned on before trying internal again. Something like 70+% of women can't come from penetration alone.
You need to become the expert on what you like. Maybe try some porn or audio erotica ([Dipsea])(https://www.dipseastories.com/). Maybe get a vibrator (not an insertion toy yet) from a good sex toy shop. (Smitten Kitten, Babeland or anything that uses the words feminist, queer friendly or women's owned). If you want to learn more about sex, consent, pleasure, kink or relationships I love Dan Savage content. He's been doing it for decades and has great advice about all of this. Don't rely on your partner to know what to do. He is an expert on himself and you are learning either. Good luck
