Dear Evan
I don’t think this is a question of normality. It is a question of perception. First stage to breaking any habit is acknowledging it, and you just took that step. What you have to decide is if you are happy with your life?
If you are then be proud and tell the world…….find a public area and declare your obsession.
If not ……..find a public area and sing a George Michael song out loud! Then you may just realise you weren’t too far wrong in the first place.
Some points concern me though.
Conjuring up images, is fine providing they don’t give you instructions
Is the doll life size and is rubber or latex involved?
