I'm sure you wash the area thoroughly each day, if not, start. If you sit a lot during the day, you can get a pimply rash from sweating and/or wearing underwear that's not breathable. 100% cotton is the best. Plus when you shower, always wash your hair first. Sometimes the oils from your head, shampoo and conditions run down ALL of your body potentially leading to clogged pores or an allergic rash. So always wash and condition first, then wash your whole body with soap and water.
