So I have friends in kinky places. Some are new to the kinkdom, some are experimented players.
And to help with the path of self discovery, I offered to write on some subject that may or not be of interest to me.
I like discussing kink, even in abstract concepts.
Age play (daddy/diaper fetishes included) versus Dom/sub relationships
I can see how they could be easily confused. I think it's normal sometimes to want to be nurtured, especially when sex was rough or took a lot out of you. I know sometimes I want to curl up to my lover as he spoons me, suck my thumb and call him Daddy.
I think I mentioned before how I have no daddy issues. No one was as tall, as wonderful, as smart and as perfect as me in my father's eyes. So this need call someone Daddy doesn't come from lack of love from my own father. It comes from wanting to feel loved, cared for and nurtured after sex took a lot out of me.
I am very open sexually, but I'm not into fecal matters sex. Heck ass to mouth has to be preceded by a couple of enemas until I feel my ass is cleaner than an operating room. For such, I certainly wouldn't be into diaper play. I actually wouldn't be comfortable role-playing an infant.
I need to look up to my mate, he needs to be strong, dominant, secure. Thus, I couldn't reverse the roles either and play mommy to an overgrown baby.
And are age plays related to Dominant/submissive relationships? Sometimes, yes. But I think most Doms would agree: it's more rewarding to have a smart grown woman submit sexually to you than having to handle a baby.
