Agreed with powerliftmike, more important than the rule of thumb time on = time off is your blood work. Get it done
As for the sex drive.... that is what PCT is about to get your NATURAL test levels back to normal or you may loose your sex drive all together along with your gains because your natural test will stop working or since it already stopped due to cycle it wont start working again.
You need to read up on PCT in the sticky notes above before thinking about doing amy more cycles and get your blood work done soon.
