Does anyone know how you can voluntarily contract your balls up towards your body? I have seen this in a few gay pornos (Aiden Shaw is good at doing this) and in a few vids on this site. Most guys' nuts contract involuntarily as they get close to cumming but I find it quite a turn on when you see quite low balls being voluntarily contracted up towards the torso. Is it something you can learn to do or is it one of those things that you either can or can't do?
Any links to any particularly good examples of this are welcome.
Cheers
