A shocking number of women are just absolute fucking freaks once you remove the consequences of being a freak, namely both intentional and unintentional physical injury, but also social consequences and unwanted pregnancy. Because I’m so open about this kind of thing I actually get a lot of women asking for advice on stuff like anal or restraints. Those women are out there, and dare I say even common, they just have to feel safe enough to let that shit out. When you make sure it’s completely her choice and she knows you’ll do everything in your power to make sure it doesn’t hurt and she’ll have the utmost privacy and won’t be forced to carry an unwanted pregnancy you might be shocked what many women will even ask to do.

TL;DR: all the weird dudes throughout history just running hogwild with rampant control / domination fetishes primarily distributed through religious extremism ruined sex for the rest of you. I was raised by fundies and a buuunch of them are hiding some pretty wild kinks under all that Bible thumping.
