Hi,Dear,Thanks for your query to HCM.
Dear I read your query and reviewed it with context to your query facts.
I understood your health concerns and feel Concerned about them.
Based on the facts of your query, you seem to suffer from-
Varicocele Left Testes with? Secondary 
Hydrocele.
The left One bigger by 1.5 times the right one- is because of the Testicular Congestion from the Venus Regurge flow from left renal veins  due to incompentent vein valves in testicular or pampiniform venus plexus which keeps the testes thermoregulated with low temperature compared to surrounding body.
So things are not normal and you need to get the USG done and Consult Surgeon / 
Urologist to treat it soon.
Hope this would help you to solve your health issues in the best way possible. 
Welcome for any further query in this regard.
Good Day!!
