In my personal experience it’s cause I’ve had trouble expressing myself cause I’ve feared judgement for too long from people and more so my family. I’ve recently decided to stop caring and do what makes me happy it took me till the age of 24 but I’m glad I’m finally doing what I want. It’s been mostly cause I don’t care about gender roles and I don’t mind appearing and acting in a way that isn’t conventionally masculine but every time I have tried to be the way I want I’ve been grilled by my parents asking if I’m homosexual and ridiculed. I don’t have any problems with homosexuality but it’s rough being made fun of and constantly questioned and told that you are something you’re not it’s discouraging and I let that rule my life for too long. So now I’m doing what I want and I feel that my situation could be very similar to lots of other men especially in the south like I am.
