That’s a good question.
I don’t think it’s a problem to hold this view for you and your sex life. Preferring a partner to not be into casual sex in my mind is just another preference. The problem comes in when people shame others for making their own sexual decisions. Even if you’re not interested in dating someone because they have a lot of casual sex, I think as long as you don’t shame them for doing that, just look at it as being a sexual incompatibility, it’s not based in shame. There’s a huge difference between “EW You shouldn’t do that!” and “I’m just not sexually compatible with you.”
So to answer your question, no, this preference doesn’t perpetuate an oppressive society according to my blog’s platform :)
