Yeah! Estradiol Monotherapy was actually the original form of feminizing HRT before they realized that binary trans women need an anti-androgen to reduce testosterone levels.

I'm also taking Finasteride, which blocks the effects of testosterone on hair follicles, and between the two medications I'm getting almost all the androgynizing effects I want with very few downsides~

The physical effects have been wonderful, my skin is soft now, I'm almost up to an A-cup, and my body odor has changed to the point that I can't tell my sex by scent alone. My sexual functionality is mostly unimpeded, though it does take a little longer to develop an erection and I'm sure my sperm count is abysmal. My hair has stopped falling out from the androgenic alopecia, and my body hair is growing in slower and more fine. And aside from a tiny degree of thinning, my villainous moustache is unaffected!

For the mental effects, I'm much more in-tune with my emotions and my libido is less insistent but still as strong as ever. It's more subtle than I was expecting, most likely because I still have testosterone levels in the low end of typical male normality. Feminine orgasms weren't new to me, I learned how to cum like a girl before I started my transition, but they're easier to reach and can be much more intense now.

Please do ask if you're curious about anything! Amab enbies who seek a hormonal transition are the rarest category of trans people but we do exist!
