This might sound ridiculous, it sounds ridiculous to me now. Last summer ((heatwave in northern Europe), yes even in rainy old Britain!), before I made the decision to present full time as female, I had to wear a gynecomastia vest to hide my boobs! Bizarre a M to F trans binding his/her boobs......yes it was ridiculously hot, sweaty, and even worse when I wear a wig. So I know your discomfort, I also know, now that I am full time femme, that I can't go swimming because my wig will likely float off!
Yes, Summer sucks as you have said.............
Cheers,
Eve
