But sure, keep with the 6th grade penis joke instead.
And viewing it as a 6th grade penis joke is more of a 6th grade penis joke mentality than just using male and female. We use allusion all the time to use words to mean different things in different contexts all the time.
male and female clearly described which goes where. if you interchange "plug" , I won't know which cable extender or plug or cable will I buy.
