That differs with cultures. The Latin cultures and some Mediterranean are very expressive and tactile. Other cultures, more Asian and some European are more reserved and less demonstrative.
How that translates into the bedroom I am not totally sure. I think that may have something to do with how an individual is raised. I was raised very openly where sex and love were discussed freely, And affection was show between my parents openly. I am from the typical Caucasian family, non religious, so there was no oppression there.
Add all that together and it might translate to having an open view of sex and affection but as to whether it makes anyone hotter in the bedroom, not sure. I am pretty vanilla, with a big slant toward romance and sensuality. I have tried other things but found them unsatisfying sexually. I know what I like and run with it.
