Why do I need to worry about who you are sleeping with?

I feel like I’m a member of a minority. This particular minority is the small percentage of people that have absolutely no interest whatsoever in what two adults do in the privacy of their own bedroom.

It’s not just that I don’t care if you are someone who throws a fit because two members of the same sex are sleeping together. I don’t need to hear from the two members of the same sex that they are sleeping together.

Please, help me understand why it’s sooo important to know who’s fucking who.
