I've hesitated to post this but zity is a place where people are for the most part, intelligent and respectful in their posts.
I've only recently been able to talk about this but I've had an obsession since I was a pre-teen with my father's penis. Yes, you heard that correctly: My. Father's. Penis.
I was not from a family where nudity was the norm but on the rare occasions where I saw my father naked, I was immediately drawn to his genitals. The first time I saw him naked, I was a young boy and he was coming out of the shower to the bedroom. I was struck immediately at how large his penis was compared to mine which was, as pre-puberty boys are, miniscule. But, it was also the crown of bright red pubic hair that he had compared to the lack of hair that I had which I didn't understand at the time that fascinated me.
Later on when puberty started to happen, I tried a little harder to catch a look at him at the urinals or to be near the bathroom when he was showering. Alas, as I became fascinated with my own body, I just didn't measure up to my father in regards to the size of his penis, the attractiveness of his penis and the unforgettable crown of bright orange pubic hair encircling it and his large, pink testicles.
I'm probably a crazy anomaly but if any one else has had an obsession with their father's penis and would like to share, I'm up for it. If you'd rather private chat, I completely understand.
