This is so true. Breast development, like erections, no two are the same. I've been around several that love the shrinkage and are all bottoms. The amount of exercise, diet and general personal appearance that I've seen I would commend the efforts. Plus they can be a ton of fun to be around.A lot of trans girls in porn cycle off their HRT and use viagra when they film.
"Real life" girls on HRT do often have trouble maintaining erections, but not all. Many no longer shoot cum, but do experience very different orgasms. Every girl on HRT that has been open with me about it says they'd never trade their female orgasms for what they experienced pre HRT.
