"Dry humping": Don't click on. That means sex without lube and there's usually anal or va**nal bleeding as a result.
"Voice kink": Haven't heard of that one but it's probably bad.
"Daddy kink": Borderline incest shit.
"Praise kink": They get extremely possessive and make you vouch that you'd never leave them then they rough f**k you in a way that should be illegal.
With couch sex: If the male is on top, then the female needs to lay of her back with her legs raised. The male then proceeds to f**k her, usually with one knee on the couch and standing with the other leg. If the female is on top, then the male lays down on his back and the girl does all of the work, cowgirl style. There may be other positions but these are the most common.
