I detect the same dual standard in Gibb Sahib's post here

What dual standard, Richard? I said I agree that, as far as sexuality is concerned, this is not a big deal—that is, one can easily fin much worse (or better, depending on your view) "displays." But so what? Contexts vary. There are several elements of contexts that, as I said, make it very clear why there would be much buzz surrounding this. That is despite the fact that you or I might look at it and think "Pfft, whatever." Hence my asking you directly (not speaking about you in third person) if you were truly puzzled.

In regards to sex, who does it with whom (age, age gaps, genders, relationships, class, race) and when (public/private, before/after marriage, after short time/long time) and why (fun, love, cash) etc all in fact matter to people - these variables reflect how people view what might be the exact same act in every case. Whether you view that should not be how it is OK, but it sounds insincere to talk as if you don't see why *other* people would be riled.
