For me it is not necessary to whip or torture girls. If the girls like whipping it is ok. But for me it is not so sexy to see girls getting whipped or enduring pain. For viewing girls getting orgasms and pleasure is the erotic thing. Seeing girls tied up is erotic. The fact that the girl is tied up during her orgasm is hot. I think humilating girls in a soft way can also be erotic. Playing with ice cubes or stuffing the girls holes is erotic. For example you can tickle the girls or make them squirt during orgasm. Or you order them to pose in a way and take photos of them. It is also erotic when you use suction cups to make the sensitive spots of a girl swell. I also don't like it when the girl is gagged. I think it is more erotic, when you can talk to a girl while you orgasm her. Kinky games like tickling or orgasm denial are great or games where girls have to do things while tied up. for example: https://www.kink.com/shoot/3585
