I got obsessed by big cocks for a time, but I know why. I would never touch another cock than my own. I never will. I don't have the desire to touch it, really. I got a big cock and got obsessed by it, next was that i started checking out other big cocks on the net. I got turned on, but not on a intimate sexual level, see it as a fetish thing. I would never do something with another man, it's against my own morals. I love girls: love how they look, smell, act, etc. I don't have that with men. Never had. I jacked off for 10 years only thinking about girls. Next was a small period with only big cocks and I also lost some interest in girls. This has several reasons: I have a penis condition called sebaceous prominence (a lot of small bumps on your penis). It sounds gross, but it is a natural condition. Girls think it's gross though, so do I. I blocked out all intimate contact with girls: I never had sex with a girl and I badly wanted it. What happened next is that I told myself that I "never will have sex with girls, you simply can't". I know that this is unrealistic, but my mind played this game all the time. If I didn't have this condition then I would have sex a million times. Anyway, I think I developed this way cause of the condition. To make a long story short: I don't have a part inside of me that wants to touch a man on a sexual intimate level. No, not because others judge it as wrong, but because I simply don't have the desire. I thought about this for a long time but I conclude this all the time.
