What's wrong with me?

Lately I've been going to the gym everyday of the week for about 2 hours a day. During my workouts I sweat so much that If I were to collect all the fluid it would be approximately 1-2L and it stinks too especially my lower body. But the thing is that I'm not building much muscle at all and although it feels good I'm thinking that I should quit if I'm not getting any results because it would be a waste of time. What am I doing that's not right? Help me please!
