My dh rinses under his foreskin every day or every other day during his shower I have NO complaints whatsoever about his hygiene. We were both born in 1983 and most men in our generation were/are circumcised and yet my dh is very happy that he was left intact. Of course, we live on the West Coast so that could have something to do with it... but still...
The only guy I know who chose to be circumcised as an adult still appreciated that his parents left the decision up to HIM since it's HIS penis. My ex-boyfriend was happy to be intact and slept around a ton as well (in case your dh tries to use the excuse that girls don't like intact penises...) and has absolutely no plans to be circumcised ever.
I also know at least three guys my age who really wish they had NOT been circumcised, but there's not a whole lot they can do about it now. The decision was taken away from them before they could even have a say in what was done to their own body (the most private part of their own body, no less) :
I also know circumcised men who are happy that they were circumcised, but I'm not convinced that they aren't just in denial And they, of course, have nothing to compare it to... just like women who were circumcised who claim that they're happy and aren't missing out on anything (and those women definitely do exist - it's all about cultural expectations...).
love and peace.
