Just a little heads up from the wife of a man who occasionally sits because of short toilet syndrome: If your.."manhood" is not suffering from similar..short syndrome the shape of the bowl can work against you in ways you may have never considered. Please think about the near future and realize that even if you don't actually pee on your..'self' you just put your little buddy in a cloud of mist that we females can not only taste but also smell even if there is no flavor. ESPECIALLY if you're unshaven. Don't sit prior to the possibility of foreplay boys.

Just a little heads up and friendly warning: when the distance between the toilet seat and the water is short (typical in old toilets) and the penis is longer than average, this might result in it taking a dive in the toilet water.

So while the answers suggesting to sit are fine, please keep in mind the above, especially if you have a partner.
