I've never thought about it that way but in my experience yes.
Two years ago I pretty much had two fuckbuddies that were regulars. One was white and one was African American. White guy was kinda 'cum and go' but he was more available then the other one. Second guy he seemed to want to kiss me more and cuddle for a bit after.
The dancer I hooked up with on vacation in August...he was literally the sweetest guy. He said, "Its been a while since I heard another heart beat" (his english was 'eh' but i got the message) HOW FUCKING CUTE IS THAT???? I wanted to take him home lmao. We laid down for like an hour after and , cuddled, and got to know each other.
Sad it happened once.
So in my experience yes but do I believe interracial sex as a whole is more meaningful? No, I firmly believe it depends on the guy.
