There is not much you can do for this, just leave it alone and abstain from sex to avoid pain and irritation. Just keep it clean so you don't get an infection and when you pee, if it burns, pee in the shower with water running over it. Don't touch it. Oh and obviously it is an open wound so do go sticking anything foriegn, including unknown penises in there...bed news.
