for me its too had to say i think mostly about one sex. alot of times the 1st thing i think of when strokin it is chicks i know or pornstars but whenever im not gettin into i think of suckin a cock. works everytime. to me theres sumthin so dirty about suckin a man off its a guarenteed nut. females have great bodys but they lack the sexiest body part of all, a cock.
