Let me try to take a closer look at a technique (in partner sex-play) that puts the focus on stimulating the urethral opening of a penis, the cock-tip aka cockmouth. It’s the exclusive touching of a very small area of the male main genital and I stated [in an earlier post of my original blog]...
There's quite a bit of chatter in the health-related and show-off forums about men's own urethras:
Show us your cumslit
Show us your piss slit
Urethra opening
Penis pisshole
Piss slit size shape
Pee hole stretching
But nothing focused just on the beauty of this part of the male anatomy...
