If I had one I would love to. That way I would be less likely to impregnate any innocent women. Like what happened to me. I have yeast in places now you could only day-dream aboot.
You haven't had any ribs removed have you? Humans are suposed be proportional and everything, which leads to men not being able to reach down that far... But I don't know, maybe contortionists can... Why would someone want to suck their own dick...?
I used to be able to do this when I was about 14. Not quite so flexible now....
