My boyfriend and I have been dating for over a year. He has been a complete C5/6 quad for 21 years. He has no movement/feeling from the chest down. He has some movement in his arms but not his hands. We believe sex is possible for us, and have read many places where quads at his level have been successful with traditional intercourse. But nowhere can we find SPECIFICS on what actually works BEST for others... Positions mainly. ANY help will be greatly appreciated.
