We probably prefer to think of childhood as a time of innocence - particularly when considering our own children.
However I think most of can remember doctors and nurses and similar games which weren't all that innocent, were they Herr Dr Freud, when they happened before puberty. When my age was still in single figures I had an experience with a younger friend. I won't go into too much detail (as we don't want to attract hits from the wrong type of visitor) but my friend would strip naked and put objects up himself. This made him coo with pleasure and he made a face I can remember down the years while most of my childhood is a blur. This prompted me to try it at home and it's the first time I remember getting an erection, though what feelings went with it I don't recall. Nor do I remember any other sexual experience until the hormones started fizzing at puberty and I rediscovered the pleasures of sticking things up my bum.
Can anyone else relate to this? Do you think early anal experiences are common and are they likely to lead to unusual interest in bottoms in adulthood? Please respond to this, even if to say no to both!
