15 months HRT here.
My sex drive utterly crashed within two weeks and never came back. I masturbate maybe twice a month on average, don't really care to do anymore than that. I was a virgin pre-transition so I can't make a comparison but sex post-hrt was pretty unsatisfying. Having my boobs or ass groped doesn't really give me any physical sensation, getting my dick touched was kinda painful and made me uncomfortable, while I just didn't feel anything from anal other than soreness. I still found it pretty hot in a mental/emotional sense to be dominated and penetrated by a guy like that, but it just did nothing for me physically. That said I've only ever had sex once so maybe it was just a one off thing.
I don't really mind being sexually mute tho, it's just frustrating not being able to satisfy your boyfriend - my first and last broke up with me specifically because of my lack of sex drive. Wish I could just find an ace or an FtM who's in a similar boat or something. I love to kiss and cuddle and maybe some groping but I couldn't care less for sex.
