Need help with my dominant gf with enlarged clitoris

My girlfriend 23f and me 20m have had a pretty good relationship. She has been on all sorts of PEDs and that has made her clitoris very enlarged. She also does exercises to make it even bigger. This is fine with me because I am very attracted to big muscular women. I’ll catch her in the bedroom with weights tied to her clitoris. She is a very dominant woman, when we are having intercourse she will hold me down and peg me with her 6 inch clitoris which I love. It is not too girthy so it doesn’t hurt. She used to use a strap on which was a lot worse but now since her clitoris is so big she can now just peg me straight up. This is all very great but my only problem is she never lets me finish. It is starting to feel like a one sided relationship where she can get all of the sexual desires she wants, but I can’t. Once she finishes inside me sometimes she doesn’t talk to me for the rest of the day. Any advice on what I should do?
