As far as I know, some soccer players wear some kind of bra to carry body sensors to measure things like beats per minute, movements, and so on.
Moreover, some cis hetero men can also be crossdressers and there’s nothing wrong with that - just a fancier way they like to dress and see themselves.
In my case, I started my self-discovery journey as a crossdresser but soon I realised that I was a trans woman trapped into a shell that had nothing to do with me.
