Your cock seems to agree as well. Look at it standing upright, it almost appears to be nodding... *laughs*
Well, we shan't deny it. Take your balls in one hand and squeeze them as hard as possible, whilst using a finger from your free hand to stroke the underside of your cock. Up and down, up and down.
When I first thought of this, I realised that it could be named 'squeezing and teasing'. Isn't that cute!
