yes many times.
a few times played as a gynae check up where in it ends with sex with just doctor, sometimes it even involved a partner for a 3some.
regular checkups too...have done all with me as doctor or patient or asistant...

Only when I was 4 or 5 with a female friend of mine. Parents were friends, we'd go play and end up playing Doctor. I remember it feeling really intense and a little confusing because I didn't know what was so Intense about probing around this girl's body. It just felt like I was going to get in huge trouble but I loved it.

Real young. I was only 13. She was a friend who, unbeknownst to me, had a crush on me.
Not much to tell, we were young. All that happened was kissing (supposedly to help me breath?) and her hands exploring me but not so far as to touch anything... at least not skin to skin.

I did once. It was with my brother and two female cousins. I think it was due to the different down there thing. We all took turns laying ended a blanket and the others would all get to put their hands down the patients pants and feel about. I don't really remember much in the way of details. I can only really recall thinking that my cousins down there felt weird. But also nice and I've wanted to touch it again since.

That was the only time we aged though. We got caught and parents were pissed. Like I mentioned in another thing, extremely Christian household. That was a not okay thing to do. Still want to do it again though, lol.
