Don't get so defeatist.
I think you really need to experiment with yourself in the absence of a male partner, and just get into whatever does it for you, *by yourself*. Literally forget about pleasing somebody else. Just do whatever makes YOU feel good.
Then later, with enough confidence, you can translate that to partnered sex.
I managed to navigate way around it as a man with an intersex condition, abnormal anatomy, fucked-up relationship with my own body, inferiority complex, mental health issues not related to my condition.
If I could do that, you can overcome whatever is holding you back too.
