It's been my experience that those who judge the sexual preferences of consenting adults as deviant have that perception because of an existing perversion in their own minds.
What does deviant mean as a mathematical expression? I was referencing deviancy as a behavior not a thought pattern. Every male and most females have a desire to engage multiple sex partners. Nice try though.
That was not a very coherent response.
Would you like to try again?
I'll try.
Every male would love to have sex with lots of women. Most women would love to have sex with lots of men. This desire does not make them deviants.
Deviant behavior is when you act outside of what is normal. Having sex with two or more people at the same time is considered deviant behavior because it is abnormal not because it is bad.. Homosexual activity is considered deviant behavior because it is abnormal not because it is bad.
I'm not sure it matters now.
