Thank you so much for the replies guys :) That is about what I thought but I'd never read anything specific (I'm against circ without needing to know all the specifics and generally don't find myself in debates) so I'm happy to have some good information.
I did touch on how the foreskin affects the woman and showing the quote in my OP I also think kind of made him think but otherwise I don't think he is interested in having an opinion right now anyway. He is circ'd which adds the whole emotional aspect of it and he also REALLY enjoys sex so its hard for him to grasp that aspect of circumcision. I'm sure videos of circ happening and that side of the story would help more but he is also far off from having kids (we hope.. he is young and in no way ready to handle it... also in his first real relationship.. he is 19) so I didn't want to push, but just plant the seed since the conversation came up all on its own.
On the bright side, I DID convince his brother who is three years older and thinks about having kids a lot more than he does... he was starting to feel bad and wishing he were intact which wasn't my intention but I'm happy to know that he can grasp the seriousness of the topic. However he is gay and intends to adopt rather than use a surrogate once he is ready for children so he might not get a say in the matter at all depending on where he and his partner choose to adopt from and which age range they go for.
Either way, they both know now that being intact isn't more difficult to care for and that America is really the only country that does it to our children with no medical reason. I told the younger brother about kellogg and he was like... yeeeah... that didn't work at ALL. (it has always been an inside joke in our group of friends about him and his.. er.. personal fun.) granted afterward he mentioned that being intact would have probably caused him to do less which is when the topic of nerve endings and so forth came up. I definitely do think I helped him consider intact as a viable, and possibly better option however :)
