Big thanks to Nikki for reminding me of what I used to get before I married
ps I'm the same as the guy who posted regarding the 'crown jewels' being ok to be fairly ok with some fairly vigorous play when I'm hard, but when I'm not fully aroused, that's when it hurts. So to all the givers, if your man's jewels are off limits when he's not aroused, try it when they're close to cumming, I find it adds a lot to the intensity of the orgasm
