Men started treating me like their guy friends, which was exactly what I wanted. What I didn’t know is that male friendships aren’t as deep.
That is also my experience - never could emotionally open or connect to my male friends. While (from time where I learned it) not having the same problem with women in relationships or friendship. I feel always a bit on guard with other men, always a bit performing. But at the same time I never made an negative experience with opening up being emotionally vulnerable.
