Is it physically possible?!
Question: To shave your own back?
Answers: To shave your own back?
I suppose if you are double jointed and a contortionist. GL LOL
If you have long ape-like arms, it should be a cinch.
I don't think so
Not really. Not unless your a knuckle dragger. Ask your gf to do it or get it waxed. Try wearing a shower cap to protect your hair and squirt nair up there.
