I dont know! I do know one thing, when someone is Obese it decreases my libido just looking at them. But on another note, I think that when a person is Obese it creates other health problems..i.e. Hypertension, Diabetes, and many other assorted health problems which are brought on by being fat. So if a person had hypertension and diabetes, yes those are health factors that decrease libido in one way or another. Hypertension and diabetes are both notorious for causing ED problems.
