In my 30s - my younger girlfriends are much less inhibited talking about sex than I was when I was their age, though, so I understand what you're talking about. However, I think women my age and older do struggle with it. My sister, who's a few years older than me, at her own bridal shower couldn't talk or joke about sex when someone gave her a sexy date kit idea...I mean, you're getting married - we know you're either having sex (or about to have sex.) But, there still exists black women who are prudes...and, regardless of the age, there exists a narrative regarding black women and their hypersexuality. We fear that, as a whole, not just black men but ANY man will only view as sexual property and may "move slower" in some sexual situations for fear of that stereotype.
I have to disagree with you. If you were my age (48) I would roll with what you're saying but at your age the attitude of Black women when it came to giving head had completely changed.
