I've often wondered if the main issue is not having a penis...I just don't know how to express myself sexually without one...or at least one as small as it is. So my experience of sexual pleasure is almost exclusively from masturbation and orgasm is exclusively from masturbation. But masturbation means I have to interact with my "wrong" genitals and sometimes can't get enough stimulation unless I unless I unfortunately use a vibrator but since that is 100% associated with women's sexuality, there's shame there that I have to resort to that. I didn't have such a hard time with masturbation until after my relationship dissolved and all that gender dysphoria I was able to ignore while pretending to be a girl so a guy would date me (the only person ever remotely interested in a long-term relationship I've met in my nearly 32 years of life) came back and worse than ever.
