This goes to all the evils of body image and sexual gratification.
In my line of salacious literature, it might seem odd to say it, but there are more things to life than sex.
If black skin - or blonde hair, or short stature, or shaved body hair or whatever - is the big thing in the attraction, then it's not something that will last.
I look for a kind and loving heart. If that is lacking, then they don't get invited back.
Love that says, "I must possess you, I must!" isn't the real deal. It is attachment, and that always leads to trouble.
