What do a woman and pigs have in common? They are both fun to hog-tie.
Was that meant to be a joke of some kind?
It was a sexual joke of course. Tying up women like pigs is fun.
Having some interesting sexual interests is normal and yours isn't unheard of but you shouldn't make a comparison between women and animals. You're essentially dehumanizing them. I can only hope you are getting consent before tying women up because if you aren't that's even worse.
