Hi.
This appears to be a case of folliculitis. Folliculitis appears on hair follicle rich regions of the body such as the groins, the arm pits ,the chest and the arms. This may be contagious and may spread to other parts of the body. These skin conditions may also be recurrent. Culture of the discharge may help guide treatment. You may need to modify your medications. Oral medications may be given if the skin condition appears to be resistant to topical medications. You may discuss this with your physician.
Do not apply any medications on the area without physician's supervision.
Look it up on internet. google gential pimples. It could be something that 1 out of 5 people in the us get.
