Often it's considered m****tation and taboo, but sometimes we can have good memories of having sex at very young age, depent of how it happens and without force.

In my case it was my nanny, a widow of sixty something down the street, who always let me sleep next to her during a afternoon nap. Always naked and she massaged me before sleep. When I was six, I massaged her too. By the time I was eight I discovered the pleasure of massaging her big boobs and by the time I was ten I discovered how pleased she was when I massage her hairy pussy. I did my very best and learned from her moanings if I did right or not.
In return she massaged my dick, it suprised me how good that felt. When I was twelve I got my first orgasm, it was very sticky.

I was fourteen when the widow pulled me upon her, grabbed my swollen dick and guided it into her pussy. Paradise opened for me and from then on I visited her as often I could.
I was seventeen when my mom found out what we both were doing. I had forgotten to lock the back door and suddenly, when the widow was riding me on top, she was faced to my mom who was curious about the noises from the bedroom.

I never saw the widow again, strangers emptied her house and I never heard what happened to her.

But there was never any force and I have very good memories of her.
