You have a rash in your groin and at head of your penis. Not all rashes in the groin region are sexually transmitted diseases (STD
), but you should make an appointment with your primary care doctor
to request a STD work up. Your story is a bit more complicated because you also shaved your groin region. When you shave, you are basically shortening the hair until it is about the level of your skin. You are also wearing underwear which is very close to the skin which can rub against the shortened hairs. The shortened hairs are more stiff and can cause pain and irritation if there is constant rubbing against it. If the head of your penis is also rubbing against your shaved skin, it can irritate the head of the penis as well. Though this could potentially explain your rash, it is only one possibility. You should get tested if you are concerned that there could be an STD involved. When you see your doctor, you should always be upfront and tell him or her that you performed oral sex and received anal sex. This information can guide them further on physical exams and lab tests. You should make an appointment with your primary care doctor to request a STD work up. If you ease the anxiety
you have right now.
