I feel the same about it. I am a natural Born bottom slut and love to be used that way.
I was 15 years old, when I was whored out to a group of men. And i loved it from the first time. And even today i go to parks and bathhouses to be used by cock after cock.
As far as I know, I am neg actually. But I want to change that as soon as possible. I want to experience the new feeling in all aspects. Thats why I prefer to have sex with poz guys. Luckily I found a regular fuckbuddy, who is poz. May be he will help me...
