how do i go about washing it off, its hard, and is quite difficult to get off, never had to do this before..help.
Hey buddy - welcome. If that smegma has built up and it isn't washing off easy (this is quite common for us uncut guys sometimes) use something oil based to help "break it down" Baby oil or a hand lotion that is oily works well. Simply retract your foreskin and rub it down good, then slip the skin back up over the head and let it sit. Then after 10 - 15 minutes or so take a nice warm/hot soaking bath or shower and let the water work with it as well. Then try to gently rub it off. It may take more than once to remove it all - be patient, and don't rub too hard or you'll irritate the head of your penis. If you'd like bud - you can PM me and we can chat off the board about this more...
Prior post is pretty well on target. In addition to the oils he mentioned, any good vegetable oil will work as well and is usually readily available in most home kitchens. I prefer extra virgin olive oil but canola, sunflower or any other type will work nicely for your situation.
