I don't have kids yet, but being European, I've never even met a circumcised man that I know of. 5yo cousin- no probs. Two half-brothers, ages 12 and 14 - no probs. My dad - no probs. Uncles, ages 25 and 41 - no probs. Ex-bfs, ages ranging from 15 to 25 - no probs. My fiancee, age 30 - no probs. Best friend, age 21 - no probs. In fact, I don't know anyone who's had any trouble with the foreskin.
I find it surprising that the human race has survived if it really is true that most uncircumcised men 1) are undesirable to women, 2) get diseases that make their penises turn black and fall off and 3) get ostracised by men who haven't had perfectly normal parts of their bodies hacked off. Also it is strange how the first I ever heard of these problems was on a pro-circ website, at the age of 21. You'd think that with the amount of penises I've seen, I would have encountered at least one of these problems
