Mine hang surprisingly low for my age. (18) I have always liked this because most women I’ve been with enjoy the sensation of having them slap against their parts when participating in sexual activities. But overall it can vary substantially. On a humid, mid temperature day, you can best bet that they hang 2 to 5 times lower than on a cold day. It’s really nothing to worry about. No women is going to complain that your balls don’t hang low enough ;D
Commitment, Dedication, Drive.
