I feel there are more women than men that have a greater emotional depth. To be understood and accepted is important, to find your tribe, and that is what we all want. And that can happen without being insecure, gay or wanting a mother figure in your life. I certainly feel more secure emotionally with a woman, that I can be more emotionally expressive without being shot down, but it does happen.
From my point of view from a young age, men are taught to suppress emotions, not express them. Maybe it is different now, I certainly hope it is. Me taking the path of talking to women over men is probably based on negative experiences in the past with talking to men about emotional topics.
And no, I do not have hidden desires to get into a relationship with my women friends. In fact a few who have wanted to go down that path, I have had to be firm with, reset boundaries. That said, in all cases, I did lose them as a friend.
There is always the potential for a problem where you get to a situation where one person develops deeper feelings for the other.
