Another way >>some<< people clean up, is to drink (or eat) there cum, they wipe it off there pubes or penis, and lick it off there finger, faster way then getting a kneenex, it's not harmful, it may seem gross, but its a body's natural thing to do, so, it may be frowned upon, but shouldn't be bad...
I will say that I have done this before, and it's way easier... but don't anymore
