It is possible that you are having a superficial folliculitis
due to excessive shaving. Use soft razors and do not shave frequently.
Change your body wash and look for improvement.
You may apply topical antibiotic
cream like soframycin
or antibiotic powder like Neosprin on the affected area. Wash the genital area with lukewarm water daily and dry it completely.
Drink plenty of water.
Ask for similar complaints in your partner. If yes, both of you may be treated with oral antibiotics
However, it is not a worrisome problem. It occurs commonly in young adults.
You shall be fine soon.
Hope this helps.
