Hi paw,

Welcome to the forum!

I was about to suggest that you use the prostate cradle for the external perineum stimulation before I saw that you mentioned it near the end of your post. I think it would be great. It may be uncomfortable at first since it is firm so just experiment with placing a pillow or some padding underneath it or between you and the cradle.

I've played with the cremaster muscles before during masturbation and I've noticed a definite increase in arousal when I raise them and a corresponding decrease when I lower them. However, I only seem to be able to manipulate them only when I'm aroused. I can't do so otherwise. I haven't tried this during KSMO as I'm typically trying to notice pleasureable feelings after I make the key sound, but this could be a good substitute for the single erotic touch that Jack mentions so often. If that increases your pleasure, then go for it!

Hope this helps,
