I too believe I have a fixation and experience many of the symptoms other guys have said they felt. I want to see what other guys have and I want what I have to be seen. My penis is my favorite part of my body. I get erect I think because I want to show off and compare but not to interact with the guy. I feel safe showing my genitals to straight guys because I know they won't touch me. I'll show anyone online because they can't touch me. I've tried the gay world but it wasn't for me I just like to look, show, and compare. With the friends who I've shown and have shown me I feel closer with them as I showed them something of great importance to me and he did the same. I feel like it's a bonding experience without getting sexual. I'm not grossed out by genitals and if someone wants to show them off I have no problem looking.
