Is it possible that your husband is not feeling well? Has he had blood work done to see if his veins are not clogging up? This can happen at a young age. If a person is constantly dragging and never really feeling healthy then how can they be interested in exerting themselves even for sex?
Parasite, kidney, and liver cleanse. Good diet for your blood type. And definitly no nagging throughout the day will encourage any man to feel the urge again.
