bf wants me to be a “stone top” after a year of dating :/

MOSTLY RANTING BUT ADVICE IS WELCOME

both trans ftm and 19YO

When we first started dating my boyfriend was on Testosterone but got off abt 5 months into dating. For a year our sex life was pretty 50/50 bc we were both switches and it was really fun and amazing and ive never been with anyone that wanted to please me in that way so it felt rly nice. At first i actually wouldn’t let him penetrate or “top” me bc i didnt think he actually wanted to but through communication he rly helped me open up in that way and it rly helped me trust him better (im just an anxious person especially abt sex) and not worry

My other relationships have always just wanted me to be dominant, which i do really enjoy, but i dont have a dick and i want to feel good too. I especially hate that previous relationships would rly push being dom onto me bc im transmasc and get mad when i act any other way. Weve been dating for over a year and a half and recently we havent had as much sex as we usually do (we still do it once a week but compared to how it used to be thats a kinda big difference). I thought it was just bc we were both busy with college and work and stuff but a few nights ago my bf confessed he worries he doesnt love me anymore bc he doesnt want to be ontop anymore and its making him feel guilty. He describes loving me in every other way and is still extremely sexually attracted to me but doesnt want to touch me bc he just wants that to be my role. I rly love him and am willing to sacrifice that but like idek how to do that bc yeah i want to be ate out, i wanna be touched and persued. Idk. Hes also gay so sometimes i get anxious that he just doesnt like my vagina but he said its not that

he said hed be okay doing me if it was in a submissive way but i dont even know how to go abt it so HOW DO I EVEN DO THAT i genuinely dont know and need advice
