If you are already using Aromasin, than proviron is useless as AI. Save your money.
You can maybe use it to lower SHBG.
I dont know why would you want to increase your high sex drive unless you plan to film a lot of hardcore porn.
I dont think you will have problems with sex drive post cycle if you do pct right (clomid+aromasin).
HCG during cycle will help also.
