Many normal workers would find themselves on a disciplinary for such comments, their careers in tatters.
Imagine a Police Officer or a Barrister making similar "jokes" & by the way, rape, which is the usual reason for spiking a drink is no matter for humour, in fact i worked in the defence industry, if i'd made jokes like that, i'd have been dismissed.
He is the Home Secretary, if he cannot function without making these sorts of comments, then he is unfit for his current role, you are just making a very weak attempt at defending him.
But as @jgw1 says, he clearly knows what a woman is (and in his opinion, her main purpose in life) so he has my vote too.
