When I masturbate, which is often, I get these odd feelings and urges. I'm not gay and men DO NOT get me sexually or emotionally excited in the least bit, but I can't help wanting to shove my beautiful cock into my mouth and suck it to orgasm, feeling every last shudder and pulse as I unload ever last drop of my semen into my willing mouth. I have never touched or sucked another man's penis, but I sure would love to be able to suck my own. Are there any other men out there that have these or similar feelings and urges?
It's more common than you'd expect. Nothing to do with your sexual orientation. It's the whole, "would you give yourself head if it was possible?" type thing. Those lucky and flexible ones already can, while quite many of us who are not so flexible only wish to be able to. So men are grossed out by the idea though, from what I understand.
I often have the same urges as you but I guess less of a concern for me as I am actually gay. Guys who can self-suck have to be very flexible - most guys can not do it. If you want to try just be careful - it can cause neck and back problems. Good luck
My body lost that amount of flexibility many years ago and I don't think there is any way to reattain it.
