Being on testosterone will also cause some growth as well, just not full growth. I know they make prosthetics that function like the real thing in and outside of the bedroom except for not having feeling/nerve endings on the shaft of course. But they do everything else, it's just not in the budget at the moment. I have a less realistic toy for personal use that simulates the correct anatomy, but it's hard to get it into the right place because what I have now isn't very big. I also have a difficult problem staying aroused consistently enough with my imagination. I would have the same problem with porn too. I also have issues with using lube and touching directly with my hand. I find it more difficult to get a grip (if there's much of any wetness really) and get enough stimulation. It also feels kind of gross to me, at least at this point. I guess before I thought about other with similar anatomy and maybe that made it less gross? But I'm more interested in/attracted to male anatomy at this point so I don't know.

Even with a prosthetic though, I'd have to find a partner who would be okay with that. My ex was only comfortable with me as the bottom during very traditional heterosexual intercourse. I've never had the opportunity to really try much, even within the realm of the fairly mundane/mainstream.
