I personally think the poster's question is clear enough. It's interesting, and not any "crazier" than a lot of things discussed here. After all, LPSG is a wide open forum.
As a gay man, I don't have children and do not plan on having any. There is a small part of me that regrets my life without ever having children, for a number of reasons that have nothing to do with my size of my dick. Nonetheless, to be perfectly truthful, since I am rather proud that I come from a line of very well hung men, in a way I regret I won't be passing it on, so to speak. (Yes, I realize how genetics work, and since the DNA of the mother factors into what is more or less a crapshoot, I know there would be no guarantee that any son of mine would also have a big dick. He certainly would have increased odds, though.) My brother also has a big dick, but alas, he has no sons. Conversely, as proud as I am about my big dick -- and I know this sounds awful -- I suspect I would be less than thrilled at the prospect of passing the curse of a little dick to a son if I had notably small genitals.
