Collage shortcuts

Sometimes I am on an erotic collage and as I show some on my website, here is my position.
Looking at erotic pictures has always been quite a pleasure for me, at least since puberty. Making an erotic picture is quite enjoyable even now, but not my primary goal at all. I am after form and expression through it. Most erotic works seem all too conventional to me, and erotism need new stimuli. A recent collage I'd qualify as erotic shows a girl.

Why does it seem erotic to me? Well there are some stereotypes like the eyes looking at you, a bare breast, the gesture of undressing, as in so many ads. Erotism comes here from a promise, from an extrapolation of the situation.
This is different from porn, where the sexual act is crudely shown. No art in my eyes. The only collages where I did so were taken from japanese prints where the scene is despicted in a refined manner. Anyway, cinema has - logically - taken over still pictures. But let's go back to my collage. Looking at it, I feel that there is some mystery in it. And that is it what turns me on - as in my other collages. Because I always want to surprise myself.
