There needs to be a score on the front page of ELU that says how many active questions there are that are SWR -and- are a thinly veiled frat boy/brogrammer asking about some sex thing. "What's a word for a woman who blah blah?"
@Aequitas If you say it like "you" or "yew", then it begins with a consonant "y" and it will be most natural to use "a". If you say it like "oo", then it begins with a vowel and it will be most natural to use "an".
