What are Sensuality, Strings of Sensuality, and Fermentation of Sensuality?

Can someone explain sensuality, strings of sensuality, and fermentation of sensuality thoroughly? I want to know, 1. What is it? 2. The main cause for it. 3. The result of it. 4. Where it lies in the dependent origination? 5. Difference between above terms. It'd be very helpful if you provide Sutta references with the answer.
