possible to get girlgasms without hrt?

Sorry in advance if tmi.

I've been exploring my gender identity and i found out i'm most likely trans (not much of a shocker is it?). I've heard a lot of good things about girlgasms and really, really wanna experience what it feels like but at the moment i'm very unsure if i want hrt, mostly because it atrophies the penis which i personally still like.

Anyone have any advice for a gal? ;-;
