I think it can get up to about 3 or 4 inches.. and that's if you're REALLY lucky.. and pumping, in addition to being on T.
I've seen some big ones.. but most are around 1 or 2 inches.
Mine is about 2 inches, I think.
It was about the size of half a grain of rice before.. now it's about the size of the top section of my thumb.. so that's a significant growth..
And it's definitely not done growing.
I suppose if you start off super tiny or nonexistent, it won't be as big as if you start off larger than average, but it grows pretty darn big either way. You'll be surprised.
I didn't really have genital dysphoria before, though. It's made my orgasms different, easier to achieve.. and just made sex of any kind better in general, however..
I can tell when I'm hard or aroused, but it doesn't really rub against my clothes.. because I have alot of fat in the way.. lol.. perhaps if I was more lean and didn't have such massive thighs, it would rub against my clothes..
