>>12921996Pretty much, two agressive inviduals of oposite sex will always engade in spontanus rough sex to dominate each other, if one of them "wins" by being more dominant the loser will lose some of agressivnes and winer gets to do as he/she wishes with loser.
Mind you it takes more than one domination to make lasting change in loser behaviour and you have to reward loser at least 1 time every 3 dominations to keep loser intrest in losing by his/her own acord and eventually droping act.
