You should meet with a licensed psychotherapist and discuss this.  Your discussions will be strictly confidential.

It is my casual (non-professional but rather "student of life") observation that children go through phases where they behave a certain way, or develop a liking for something and experience it to super-saturation.  But then it passes.

If you are still practicing at this high frequency, you seem stuck in the same infatuation.  

Shoot, at least you're not a serial killer (I hope).  

Peace.

Sounds pretty normal to me...

Very common, very normal!

What is more natural for a child than learning thru the senses?  Learning how to self comfort and pleasure?  It is likely you may have been touching yourself before three... got caught and were given the impression that touching oneself is wrong, therefore creating the clandestine sense of it all.

You sound as if you are one of the healthier ones, to keep your sexuality open and flowing.  Many people associate shame and guilt and therefore STOP touching themselves.  Some people relearn when they are teens, some later in life, the very unfortunate - never.

I myself have fond memories of the misuse of certain innocent children's toys, a somewhat discreet manner of sitting on my heals, reading found girlie mags in the vacant lot with my grade school friends, games of doctor and the like, friends brothers (especially if older) were a favorite...
I never extended these fantasies to cousins or nieces, though as long as the thoughts remained in fantasy land and we are talking child fantasing about child, there is nothing unusual about that either.

Of COURSE these experiences have impacted other areas of your life.  Everything we experience helps comprise who we are, ripples through our future days, helps shape our personality.
Which aspects don't seem "quite right" to you?  
What don't you feel capable of asking?

I started when I was around... 6 or 7.  Before that point, I had never taken much interest in 'down there' beyond normal biological functions..

Actually what started me masterbating was my next door neighbor's (and best friend at the time) discovery of his parents porn stash.  He discovered that he got a response from his penis when he played with it and watched the porn at the same time, and he just had to show me cause it was so cool! So, I started trying it too.. LOL.. the mind of a 6/7 year old..

I remember doing it alot as a child, but not really an abnormally large amount..

The only reason I learned to hide it was because I thought something that felt that good had to be wrong!  A few years later when my mom caught me doing it once, she took it in stride and said 'we all do it, don't worry about it.'

BTW I'm new here
