I think most folks pick up on their unusual desires early on -- like around 8 or 9 years old.

I saw a Penthouse pictorial of 2 women having sex. Tame by today's standards but I was hooked. The women were sexy, the action was hot and the pictures of two hot women entwined skin to skin were mesmerizing. 70 or 80 live and in-person 3somes later I still have the bug. I just can't get enough of watching two hot women getting it on. Yum!

I had seen her maybe 6-8 times.   This occasion she was kind of woozy, and I asked "What gives?"

 
She told me she had just done a golden shower with a guy, and so had to down a six pack before hand.

 
Question marks hovered over my head, so she spelled it all out to me.    I was sort of disgusted by the thought of it.   However, in the ensuing weeks I started to become intrigued by the idea of a gal peeing on me, and so asked her the next time I came over if we could do same, and we did.

 
Odd how things like that work.

a hot hooker turned around, stuck out her ass and smacked it. I said, "Ooh! Can I do that?" She said yes and a Dom was born.
Fast forward a few years to another girl. I was lying on the bed while she was on her hands and knees blowing me. I smacked on the ass and she stopped long enough to insist, "Harder!"

Not sure if this is considered a kink, definitely not a verified kink since I haven't repeated it but surprising nonetheless. I recently hooked up with a stereotypical MILF, think Stifler's mom. Blonde, pretty, thick, big boobs. Of course at this point in my life MILF just means she's my age lol.  

She's riding me CG and I'm sucking on a tittie when I begin to blow my load. This was an uncovered civvie encounter so she must've felt me beginning to cum. With one hand she's pushing my head into her tittie to keep sucking and with her other hand she starts petting my head and saying "that's a good boy" "keep cumming my good boy" "be a good boy and give it all to me". Surprisingly it turned me on a lot and made the orgasm better. I don't think I have a mommy/baby fetish but it sure was nice being coddled lol.

just like hard to say when I graduated from crawling to walking, and from babbling to talking, but somewhere in my early 20s, I figured that there was more to life than just vanilla sex. LOL  

 
There was a very young girl named Kristy I used to meet up back in 2005-07. The girl would smack me silly, and spit on me.. Then we would get in the shower and make out vigorously. Couple of times, she even gave me a very warm golden shower. It's true what they say about redheads. They are a frisky bunch. Too bad she moved to Richmond for school and we lost touch.

Yeah, ok...call bullshit, but around that age, me and the rest of the 6th grade guys thought we were all on top of the world; finally reaching the top in elementary school!  LOL

My 6th grade teacher, "Mrs. H" .....wow....always dressed in those sexy dresses which showed off those killer legs and she ALWAYS ALWAYS wore nice heels.  

That began a lifelong obsession with looking at women who had nice legs and knew how to show them off.....in dresses or skirts.....  

I always said that a woman's ass and legs are the last thing you see as she passes you and of course you sneak a look back and see it.  

Go on, deny it.

and fucked me in the ass. i actually enjoyed it. Although, she couldn't quite get that thrusting thing going.

DDLG - Daddy dom/little girl

I discovered at age 18 or so that I was into older men, especially the daddy types. I love to be told what to do and punished when I'm bad and rewarded by daddy when I'm good. I think I realized when I was on Tumblr one day and got really into the ddlg posts. Lucky for me, a lot of older men love playing daddy to a spoiled little princess
