Ok hun. I get these all the time. You have nothing to worried about. All it is, is inverted hairs and or zits from sweat and shaving.

You need the doctor to diagnose the problem. This can be some common infection. After the infection is taken care of , you may do 'deer exercise for woman' to enhance your sexual energy. Google the above phrase.
