Well I researched it, you can either have a doctor do it, or they have products you can buy that remove them like this one ... www.hemorrhoidshemroids.com
You should see a doctor. If you have a "skin tag" on your anus it could be a sign of HPV. The tags can be burned/frozen off by a doctor or a certain cream can be applied to gradually take them away. The virus does not go away and is easily transmitted. Many people have HPV without any signs or symptoms.
