sounds liek you are being a little rough on yorupenis when you masturbate and after, even fabric rubbing on it are not feeling good. Try to get yrou hand on a decent lubrication when you masturbate. KY and others are sold in pharmacies and other stores. But if you aren't up to making a purchase, raid th ekitchen and use some vegetable grease.
