Vaginal orgasm

Dude, I'm so horny, I'm so fucking horny. I want someone to just stuff me full with their hot thick cum while someone else fucks my throat and makes me gag on it. I want to be fucked doggy style in a park until I piss with nothing but a collar on. I want to be fucked in front of a group of people who'll fuck me after, all at the same time. I want to be fucked so bad but I can't even orgasm. I can barely cum, and each time that I almost get there, I have to stop cause it gets too much. That shit hurts man, and I end up just getting frustrated that I can't cum. Not a good thing that I'm into BDSM cause it's hard for me to get into the mood. How the hell do you cum? I've tried using a vibrator, turned it off cause it got too much. I've tried using a dildo, didn't work, was too small. I've tried using my fingers, didn't work my arms kept cramping and kept pulling my leg muscles. Please I just want to be able to cum
