This could indeed be folliculitis or inflammation of the hair follicles. The bumps along the shaft may be sebacious prominence or fordyce spots. However, due to the sensitivity of the location of these pimple-like lesions, the usual antibacterial creams or ointments need not apply. You can use antibacterial soap instead. Keep the area clean and dry. Wear nonconstrictive clothing to prevent unnecessary hair removal. If it persists, it would be best to have this evaluated by your doctor. A referral to a dermatologist may also be warranted.
