Any woman should run in the opposite direction of any man who takes pride in being straight, just as they should from any men talking about how sex positive he is. Men don't care about you, they care about passing off their fetishes as politics and strength of character. Some will try to pass it off as protecting women, then start whining when women don't reward them with sex for it. It's always going to be a horrible misogynistic cesspool and you'd think that women would learn this by now. Being confidently "straight" generally means going through the endless mountain of misogynistic straight porn so that any alternatives have simply not had time to get on your radar, or having patriarchal beliefs about women strong enough that you refuse to even consider anyone else being placed in that role. Ironically this sexuality is more in line with genderism: these men have a fetish for misogynistic feminine caricatures of women that they've been sold by other men, not for actual women the way you might see in lesbians, hence the extreme hatred they harbour for women despite said sexual attraction. Male "heterosexuality" is very much divorced from an attraction to women, it's either a fetish for lifeless caricatures that they've been trained to rub themselves to all their lives, or it's violence and entitlement aimed at social inferiors.
