I know of several people who have actually fallen in love with people over 18 years of difference. They were perfectly happy together.
And I'm sure there are, however those kinds of relationships are a rare thing, and are becoming even rarer. I apoligize. However, the majority of those sorts of relationships, with that large of an age gap, atleast within America, tends to be more for less noble purposes. Either she is with him for money, and nice things, or he is with her so that he can have a young thing on his arm and in his bed. And usually, the only thing they actually have in common is their exploitation of eachother. Which was what the statement was based on.
As for the actual heart of the matter, unless you were having unprotected sex, or were planning to have a kid (which most places recommend a blood test), there really isn't too much wrong with that whole "she might be my biological daughter" kinda thing. Now hold your pitchforks a second. In many places you can actually have more genetic similarities with your neighbor than your child (even when you are the biological parent). This is because although 50% of their genes may come from you, 50% also came from someone else. Whereas with your neighbor, if you share the same eye color, same skin color, and same hair color, chances are that you may have more than 50% in common with them genetically, especially if you happen to live in a small community. In general, imbreeding is only a problem in those rare cases when a recessive gene is passed from both partners, in which case the offspring won't have a healthy gene to make up for that weakness (blond hair, blue eyes). But as procreation isn't an issue, that rare chance of both recessive genes being passed on isn't an issue. As far as the other "Ick" aspect to it, neither of you had any relationship beforehand, neither of you had any knowledge beforehand, so there are no intentions of incest in the act. It's not like you helped raise them from a child, and imprinted in their life as a father figure (that came later). Sure, once you find out about a blood relationship, there will be an awkward moment, and the romance may be gone, but before then it really isn't any different than dating anyone else.
I mean, there is a reason why Woody Allen is considdered a sicko, and it has little to do with his movies. He adopted a child, and then when she was old enough, had sex with her, and eventually married her. Although they were not blood related, it is still a disgusting act because he was "father" to her.
And as said, even those chances are very remote since most sperm banks trade their stock with other banks around the country to prevent that sort of thing. You actually run a greater chance of running into a long lost cousin, or in some cases, a sibling. I'm not trying to sell you on incest here or anything, it's still sick. The moral of the story is really that you should be more careful about who you sleep with, sperm donor or not.
