Like I tell all guys, young or old, get rid of the briefs and speedos and get boxers cotton boxers, you maybe developing an allergy to no cotton briefs, If you can once in a while go without underwear, and make sure when you do that you are wearing a pair of old jeans, or shorts if you are going to spend time at home, You need air in your testicles, if you can sleep in the nude or without pants or shorts, this will help.
