I just want some warmth and wetness around my cock when I lay in bed at night. Sometimes I therefore wrap a towel soaked in hot water around my dick before I go to bed, put it in a plastic bag and close it up with a few rubber-bands to keep the warmth. As I sleep I thus often dream of having sex, and the sensation is quite close to the real thing. The trick is to wrap the towel tightly to apply some pressure to the shaft, so when the dick erects it gets tight and nice.
Anyway, my mom is complaining that the hand-towels in my bathroom smell vicious.... Perhaps I should just get a fleshlight?
