I think the general lack of testosterone is what makes the biggest difference. That being said, my brain functions very differently from that of my other male friends. I can remember well my teenage years and being exasperated at their behaviour, when my friends partied and drank I'd be there making sure they were eating and cleaning up after them so their parents wouldn't come home to a mess. I just thought I was strange, girls weren't a priority for me. They killed themselves to get any girl to look at them and married the wrong type of women. Now they're either divorced or miserable in marriages that being held together by children.

My relationships have been wholly emotional, many a relationship ended because of a lack of sex. My current partner prefers toys so it's worked out well, even though I'm on testosterone now and I have a libido for the first time in my life I still don't function like a normal guy... It just sucks
