I basically had suppressed my emotions my whole life. Since puberty I could count on one hand with fingers to spare the number of times I legit cried before transition and it was usually something like death of a pet or family member.
Some of thst was from running on the wrong hormones, but plenty of cis men are able feel emotional on T. A lot was being scared of showing I had emotion.
I've faired better as I'm not 2 years into transition and already feel like a different person.
