Most men, including white men, think like this, even if they don’t admit it, because women can get pregnant and a woman who gets around might cheat on you later (and could lie to you about it). In Western culture it’s acceptable for both sexes to date but a lot of women still lie about the number of partners they’ve had. The difference is that in our culture, the divide is so stark.
I would question this guy’s mentality because he’s calling girls sluts.
