Since I am a man, I cannot tell out of own experiemses, even though I have experienced similar things, but i tell something about a female playmate I had since age 5.
She wanted me to play doctor with her. Especially she wanted me to spread her labia. and look inside. I asked her if the doctor did so, and she confirmed. She also told that she had regular exams in her vulva because of certain problems. One time she was sick for nearly two weeks. I asked if they examined her vulva during her sickness, and she confirmed.
I was not surprised at al. On the contrary, I anticipated that answer. Even if this was the first time a girl showed her genitals to me, I did not get not surprised about what I saw. I think the reason is as follows.
Before age 7 I had regular exams in an establishment called “Kontrollstajonen”, menaing “The Control Station”. For some reason, my exams were more thorough than the majority, and I was sedated so that I do not remember much of it explicitly. Still I have a lot of pictures in my memory of singular scenes involving both myself and other kids. Usually there were several kids there at the same time and there were little privacy.
On of the things I remember is a girl lying straight on an exam table, the doctor doing something inside her vulva with a long instrument, spreading her labia with the other hand,. I saw it through a door that was open, so I cannot tell exactly what was done. But I think the doctor took specimens from her urethra and bladder with a rigid catheter. They did the same with me in much the same manner. I think this picture actually was from my preschool physical at age 6, which was a rather long even.
