Both high estro and low eastro can cause this , and for me its extremely hard to tell if I have let it go too high or pounded it too low. Cracking joints are usually my only indicator Im too low.
In any case I recommend trying three things , 1st is get back on a stable and consistent dosing protocol for your AI , 2nd is 100mg of Proviron ED for 2 weeks then adjust or discontinue as needed. 3rd is are your balls hanging loose and full ? Or tight and possibly shrunken ? If the later is the case do a couple shots of HCG . Even though HCG in high doses can cause increased estro 500-750 E4 days is not going to give you trouble , and believe it or not HCG has helped my sex drive because when your balls are full your body wants to empty them somewhere LOL
