Okay, what if the alien creature wants to fuck, but it cannot speak a human language, but an alien language, which is not imagined anthropocentric, where something like agreeing and disagreeing to something has the same tone as when a human agrees or disagrees to something? No matter the language, you still know if somehuman agrees or disagrees to something based on facial expression, body language, and tone, but what if the alien really wants to fuck me, but his behaviour is the opposite of what I would expect someone wanting to fuck be like for a human? And assuming that John Harkness very likely meant legal sexual maturity with the third point - what if the legal sexual maturity of the alien society is like 6 years old?
