This is extremely disrespectful to women. They aren't objects.
It's disrespectful of the trust that your partner places in you by engaging in what is fundamentally a private interaction to share it publicly without their permission.
When can we give up the idea that sex, for no other reason than gratification, lust and desire is in any way bad?
When can we get over the idea that women don't want sex? That they shouldn't be allowed to want sex? That they should feel sorry for wanting to have sex?
If you accept that women should have the same rights as men, it should follow that they should be the one to choose when, how, where and whom to sleep with -- and how often.
But of course, if you don't, if you believe that women are somehow inferior to men in matters of judgement, then your comment makes perfect sense.
That is not an argument I can support, though.
