Scared I will Never Get a White Woman Pregnant

Although I've never liked her outside relationships, I've always just accepted them as her nature (with a few extreme exceptions early in the expansion of her sexuality): she's a bit younger than I am (she's 34), she's always had a "thing" for black men, and she's always attracted a lot of attention from them. Her ** drive is much higher than mine, and I think she's just one of those women who need more than one man in their lives in order for them to be happy. I know they exist, and I think she's one of them. I believe that all of our children were fathered by me. None appear to have any mixed blood in them, and while none of them look like me, they all look like each other, meaning they are pretty clearly siblings. I have no reason to believe that I didn't father one or more of them, but who can be sure? (And no, I've never DNA tested them, and won't do that without good reason.) My wife is very outgoing and beautiful and flirtatious, and she certainly would have had opportunities with innumerable white men, as well as blacks. As for handling it, I do believe I've done a good job of coping, yes. It's because I'm proud of my lady, and always happy to be seen with her. However, my unease about Saturday night -- and her public display with her dark companions -- makes me think that's about to change. I could be wrong about that, and I hope I am.
