I was insulted by the implication that I should be ashamed of sex or of talking about it, or that I'm supposed to consider this lofty magical think that has to be a big secret and people can't be open about.

I'm also guessing that I'm supposed to be 'repulsed' at the hypothetical software, that it might let two men talk to each other too, eh?

Ironically the solution to both are the same. People have different opinions, societies tend to have evolving, and shifting views about social networks or social behavior just like they have about sex in the past. Going around being all judgement of either set of behaviors is not productive.
