If we were sitting side by side in a restaurant booth and if you slipped your fingernails along my thigh to just before the inseams meet and tickle/scratched the denim there…

Well actually this is silly because chances are extremely good we haven’t have been sufficiently introduced for you to contemplate doing that, but you really wouldn’t be able to verify what happens, but I just wanted to let you know that if you did that then all the hundreds or thousands of little muscles in the loose skin holding my testicles would tighten up and away from your tickling fingernails.

I’m not sure what it’s about. It’s not really about arousal (if you did that I might get an erection too but that’s different.) Instead it’s more like a reflex related to tickling, or changes in temperature, or surprise or some other kinds quick emotional shifts. Actually chances are your nipples do something pretty similar and maybe for similar reasons when someone’s fingernails tickle/scratch the fabric over the outer undersides of your breasts. Although chances are fairly small that anyone would do that to you in a restaurant.

I’ve mentioned this elsewhere but I think it’s funny that a lot of people (me for instance) think crinkly erect nipples are sexy even though plenty of us (me for instance) know perfectly well they don’t really signify arousal, at least not directly, any more than crinkly testicles do. And I’ve mentioned this earlier but I think it’s funny that not so many people think crinkly testicles are sexy the way crinkly nipples are.

But if neither nipples nor testicles** pparticularly signal arousal that obviously doesn’t mean playing with them isn’t arousing. I mean, either way they’ve got tons of nerve endings and especially when you’re already feeling erotic the sensation can be extraordinarily lovely. And either way it’s fun to softly pat and play and stroke them tight and then warm them soft again with palm or gentle suction… and then tickle them hard again. And I’m not sure there’s a good way to verify this, but I suspect that crinkled testicles and nipples respond to handling about the same as well, where roughness sometimes works and other times is completely cringe-inducing — sometimes from one moment to the next. It’s certainly the case, though, that sometimes partners have played with me too long and it stops feeling nice and starts feeling sore, and other times I’ve played with a partner too long and she’s asked me to stop… so if nothing else, even if it’s not an exact parallel (for instance some people like their nipples squeezed hard whereas…) it’s something to think about.

You’re welcome to chime in if you feel otherwise, of course. I’d invite you to do the inseam-tickling trick with someone you’d feel comfortable doing it with and then ask him about it, but you’d probably want to communicate clearly with them first.

[** Ok, ok, technically the little muscles are in areola and scrotums. I just prefer to say nipple and testicle. —fl]
