It varies for all sorts of normal reasons. In many UK big cities it is normal to see white mothers with coloured babies. That in itself sends a clear message. It also common to see white female teenagers knecking with African men on the tube. In some areas of London I is highly mixd, while in others it is not so. However even in the areas predominantly white it was still possible to find pubs where white women went into expecting to find black men. It goes back a few years, but the Swiss Chalet in Muswell Hill was like that. Bars in Bayswater were often predominantly Muslim and white women went expecting some 'fun', while I recall a bar in Knightsbirdge that was predominantly 'upper crust' white females and rich Arab or African men.
However in areas in the countryside, or predominantly white (98% white) the curiosity factor is also a drive, and in East Angla black American servicemen were often the centre of attention.
In Africa all white females were the centre of attention whether in a park, shopping mall, restaurant, clubs or bars, and what is normal is them appreciating being the centre of attention and eventually reciprocating.
