I am comfortable expressing everything except frustration around women because it is misread as anger, even when flatly stated as "It is frustrating that this keeps happening" in a monotone voice.

Actual anger is received fine, because venting is fine. But frustration leads to anger or something. Pretty sure it is just reminding them of someone else who expressed frustration and then blew up in anger. Like the anticipation is worse than the actual thing.

I used to be more reserved about expressing positive feelings towards other men due to social conditioning, but I stopped caring a while back and tell all my buds I love them every once in a while.
