Thanks for linking to the Ada Initiative reply. After reading that, I agree with you (and them) that this talk was likely to result in more sexual objectification and technology-skill-dismissing of the female attendees, in today's society.

It would be better if we lived in the society where you could talk about sex at technical conferences without making the women there feel threatened or objectified because no-one would threaten or objectify them as a result of the talk, but we aren't in that world yet.
