Cool air makes this Uncontrollable

So, when I have my diaper changed, I have this weird thing happen that I 100% cant control. It's kinda embarrassing.

I'm laying down, and my diaper is taken off. My labia is spread and the coolness of the air hits me but when they wipe me and clean me up or do something else to me in that area, I pee . Not a lot. It's enough that you would certainly notice. An ounce or so.

When I am changing my own diaper, I'm used to it. No biggie. But when I have to go to the hospital or when I have to go to the doctor and a nurse or someone changes me, its embarrassing.

Last week, I had to go to my gyno. I was sitting there, made sure I had a dry diaper on and when the doc came in she unfastened my diaper and began her exam. She put the speculum in and I peed on her hand a little. When she did the bimanual part, more pee came out on her hand. She cleaned me up after the ky and dang it, more pee came out. She sent her nurse in to get a urine sample with an in and out catheter and as she was cleaning me up, I peed a bit more.

Does anybody else do this during diaper changes?

It's hard to say with my incontinence. I constantly leak small amounts. Not near an ounce at a time unless getting up from a laying down position.

That's why I don't remove the wet diaper completely until the fresh one is ready and cleaned up. I don't waste time to get in shower after removing the diaper.

Drying myself as much as possible in the shower before getting out. I put an incontinence penis clamp on for drying off. Than removing it when the fresh diaper is under me ready to be taped up.

I do get a bit more volume depending on how long between the clamp installed and removed. As far as releasing urine because of a diaper change done by someone else? I sure that's not my case. I'm wondering if it's not because you're being turned on, nerves or possibly both.
