Sexual fantasies are a very funny - human - thing. Some can be very liberating.
One of my first sexual fantasies, and definitely one of my favorite ones which I'd LOVE to jerk off to night after night, involved me having a sexual and emotional relationship with an uncle (a fictitious one) - not a father. In order to justify (in my mind) and spice up this fantasy, taking it out from the moral rules of our society, I fantasized about my uncle being a "werewolf". - This was more than 10 years before all these Edward and Jacob, vampires vs. werewolves books and movies fashion. In my fantasy, I was part of a family (and a secret, underground society) of vampires and werewolves. Vampires and werewolves weren't of different, opposing clans. You would be a vamp or a were depending on sheer genetic luck. My father was a vampire. My uncle was a werewolf. I liked it so much that eventually I had 2 werewolf uncles as my lovers.
In real life I always had a normal-distant relationship with my own father, most of the time. I am gay. - A fun, ironic fact (and a tragic one, you might also say..) is that when I was young (7-8, 12-13) I always felt VERY uncomfortable having to take a shower with him. I couldn't conceive the idea of 2 naked men taking a shower together as being a right thing! This includes the times when I "accidentally" had to see him or he saw me naked.
My father passed away whey I was 19 years old. Years later, while I was jerking off and thinking of the reasons why I had that type of up-tight relationship with him, I found out that I was the reason of my problem. Sure my father was also part of it; but mainly, I wasn't very confident about myself and about my body.
After jerking off thinking of him and I having sex together, a ton of emotional bricks dropped off my back. At last I felt FREE from that troublesome aspect of my life.
Lastly: What do you guys have to say about that wonderful "good-morning" image of seeing, thinking and fantasizing about your father bending over the bathroom sink, butt naked, shaving. Inspirational!!!
