I don't know that I ever had a hard and fast blueprint for a mate. It may be a bit racist of me to admit, but I once quipped to my mother that any black girl with enough going for her that I might be interested in marrying her would probably not be interested in marrying me!
In general though, my tastes have run to my own kind, e.g., women of north European ancestry:
Wife #1: Irish & German
Wife #2: Norwegian and Irish (favored the Norwegian side strongly in looks)
Wife #3: 3/4 English, 1/4 Irish
Given what disasters my first two marriages were, perhaps I might have been better advised to have looked elsewhere. On reflection, just about every dirty deed that has ever been inflicted on me has been by white people of north European ancestry. So screw Aryan solidarity!
