Understand, our language is still emerging from a male-dominated age, when it was 'accepted' that of course, men had 'sexual appetites' that needed to be satisfied; but that such behaviour in a woman was an outrage, a disgrace, made her the lowest of the low. So, we have wink wink, nod nod euphemisms for men, like 'womanizer', 'philanderer' - and even role models: 'Casanova'; but for a woman, the words we use are like swear words - 'slut', 'whore' (even if the woman does not expect money) and more! - more up to date: 'slag' 'town bike'.
Like the law, language can take some time to get up to date when in some men's minds, time stands still.
