.... come on man. No, just no. My girlfriend is 1/8th native "Brazilian Indian" (you get me, pocahantas), no black blood. Yes, Brazil has 2nd highest African descendants outside of Nigeria but did you look at those girls? Not dark skinned, just Brazilian.
I don't care if you're at that beach with your wife, GF, mistress, friends or whatever. How can you not stop and stare at that view.
I managed it. Thing is, you don't perv, you say "so that's what they mean by big asses here" or "that's a huge ass" - in a matter of fact way. This creates a conversation with the subject matter in plain view to be discussed. Say she has pointy knees so you wouldn't be into her and gf will be all right

You guys need to learn this art. Find something to say is unappealing about such women and bring your partner on board. Then perv away.
