Im a straight sub male with a particular draw towards humiliation and degradation, which leads me to ab and sissy play. I'm not an adult baby, I have no draw to behaving as a baby, in terms of playing with toys, colouring in etc. For me it is more of a sexual power exchange, being dressed like a sissy or a baby is humiliating and degrading and god does it turn me on.
It wasn't something I had ever considered before my first online domme, a wonderful American lady who slowly corrupted and conditioned me to connect age play to sex so strongly it's still with me 8 years later and has only grown. I find myself craving having someone there to belittle me, to reduce my self worth through outfits and forced behaviour till I'm shaking and whimpering and desperate for her touch, regardless of the cost. Sissy falls very much under the same heading for me.
So that's a short overview, be keen to hear from any others who have a similar thought process towards kink
