I suppose this is one of those things that should be noticed but is not...

Anyway, I have a tight foreskin tip. I'm too lazy to deal with it, but what I've noticed is that during arousal of my penis (just thinking sexual thoughts, not actually retracting or anything) the prepuce will dilate bit by bit of its own accord. However, don't expect a black hole to appear..... However, it is then "easier" than before to attend to such matters.

This is not my diary lol, so my point is that one should pay attention to this fact. Obviously it may sound strange, but this is no doubt due to the dartos muscle structure of the genital skin or such, if I am not mistaken.

Yes, the muscle does contract and expand according to arousal and temperature.
