If it makes any difference, as a kid I never knew if I was or wasn't. My knob sorta is half covered when flaccid, then when erect looks as if it's circumcised, with the skin unable to be pulled completely over the tip. Either way, it certainly hasn't effected my sex life. Totally agree with the comments about washing, cut or uncut you've got to wash it properly and regularly. It will still stink wether you're cut or not if you don't clean it properly.
