How old were you when you had first Rectovaginal exam?

So to all you ladies out there. I have a serious medical fetish for Gynecology! And especially the recto vaginal and rectal exam portion! How old were you when you had your first rectal exam and what did the KY feel like? Also do they spread your butt cheeks and look at your butt?

My gf has always had them beginning with her first gyno exam when she was 14. And yes, as part of it, he spreads her butt cheeks and looks at her anal opening.

I was 15

Do any women here stop putting any in their butt before an gynecologist appointment, thinking it will be stretched out and the doctor will know? Or is it better to, and see if he lingers longer than normal with your rectal exam..?
