Oh girl yes! I did the side by side once and I was like asdfghjkl;
Vanilla sex can be boring. I like to be adventurous and sadistic.
My favorite position, the one that gives me the biggest orgasm, is one where I sit on top and hold a knife to his throat as we fuck, then I strangle him. That turns me on big time.
Problem is I'm impulsive. I've lost control in that situation. Sometimes when I start strangling someone, I can't stop myself from trying to kill them. So, I don't tie them up beforehand. That way, if I lose control, they can stop me from killing them.
Okay when and where do we start?! 
If a girl cums when I'm standing I generally don't hold her up. If she can stand on her own more power to her. When a woman has an orgasm, I like to make it worse. Like torture... If she has to fight to stand while having an orgasm I believe it heightens the pleasure for her. If she falls to her knees I follow her to the ground but I attempt to stay inside of her and I continue to fuck her. If I'm eating her I usually keep eating her through the whole orgasm and after because the clit becomes sensitive during and after an orgasm. I've had women try to push me away while she cums but I just grab hold of her thighs and keep eating. I torture the bitch with pleasure.
