One of the alien gurus makes some amusing assertions about sex and then gives some good advice that made me smile.
"Where there’s a wang there’s a way."
And the tongue-in-cheek paraphrasing of William Gibson's
"The future is alreay here - it's just not evenly distributed"
"Sex is universal, it’s just not evenly distributed."
But what I liked most was this advice on how to treat a sexual partner from another species:
"...don’t giggle when the other entity takes their clothes off, secure enthusiastic consent, don’t mix silicon and carbon without extensive decontamination protocols, tidy up your house if you expect to bring someone home, don’t expect anything you wouldn’t offer, remember that every person is an end in themselves and not a means to an end, don’t worry too much about what goes where and how many of them there are, don’t mistake fun for love, try your best, be kind, always make them breakfast, and use protection."
