How do groinal responses feel?

So I just had an ocd moment.. my daughter had her head in my shoulder and all of a sudden I started to worry about groinal responses.. well of course I start kind of clenching myself to try and make sure I don’t get one and to stop it.Which doing that and worrying always makes me focus so much on it that I get one. at one point the weird feeling almost felt pleasant or tingly but it’s hard to describe! I can’t go down this rabbit hole of guilt again. Anyone relate?

I used to use an industrial machine that could really have broken my hand, and in the moment my hand needed to move out of the way, in that instant before I moved it, the tension of the situation gave me, consistently, reproduced on demand, a not at all unpleasant sensation in my groin. Kinda tingly. Very similar to a sexual sensation. Nothing to do with sex. Not a thing. Just an anxiety spike. Experienced dozens of times, without fail. It was a fascinating experience and completely proved the theory of the groinal sensation.
