i think sex positive movement make it hard to say no.
Ideally you can, woman can, man can, children can.
but real world it's more Elaborate Trap.
"my ex did it for me..."
"every one does that..."
"you think you are special?..."
and the culture says how good and confident woman loves sex and kinky thing.
why all have to sex positive?
some of woman and man want to sex with really really loved one or
save sex(?) for marriage.
