Sex was around long before your sister and her husband started experimenting. I've found that people who brag about their sex lives usually don't stay together long anyway. Who cares about her positions. I never liked discussing sex with relatives anyway, especially siblings. Whose business is it? Your sister sounds to be starving for attention. I feel sorry that you have to listen to all that. She's being pretentious. Tell her I said so.
