Hi there.
I'm a CIS male but I've been dressing up with bras and panties under my regular clothes since around 8yo.
I've read a lot about the phenomenon, there are distinctions between different motivations behind why one would dress up as opposite gender.
When done for the purpose of arousal, it's called cross dressing, since this has been going on since before puberty, So it's not that, it is more based on gender dysphoria, and I think it's called gender non conforming.
I wear a 50DD bra and have a pair of silicon prosthetic breasts that I wear to fill out the cups properly, only been this overt for about 15 years, I also started wearing dresses and heels on occasion.
I haven't done any HRT, for although there is an undeniable feminine component tonmy psyche, there's also a masculine component and I feel incomplete without either side.
I am used to wearing male clothes and female underwear and prosthetics underneath. I moved to NC some years ago, and they passed laws that don't allow trans people to use either bathroom, and allows doctors to not treat trans patients. Last I heard those laws were challenged and repealed, but then 47 reinstated them federaly, not surw what the current status is, but I am back in the closet till I know I won't be deported to a Salvadorean gulag.
My greatest wish us to grow real breasts the size and shape of a young Samantha Fox (super perky, looks like she's smuggling torpedos under her shirt... I tried to get AI to give me an image near what I'm looking for.
