Not to have this debate, and I don't have any hard data, but here's what I think: TMS (Traumatic Masturbatory Syndrome) only affects circumcized men. The fine-touch nerve ending have been hacked away, so the penis needs more pressure to be stimulated.

I wonder if any studies have been done...anecdotally, I've heard that going down on uncircumcized guys is "easier" because far less suction and/or pressure needs to be applied...also, that the sex is differrent, because circumcized men need to "pound" their way into orgasm, whereas uncircumcized men can "glide."

So...any uncircumcized TMS sufferers out there? I very much doubt it.
