I dont know if anyone has noticed this, but when I take an aromatase inhibitor like a-dex, letro or proviron for a few days, and I try to have sex, its incredibly difficult, if not impossible to orgasm. Libido is otherwise normal... Is this just me or has anyone else noticed? Its a little embarrasing tbh... Without the AI, I am fine... Could this be a symptom of insufficient estrogen, or possibly related to prolactin...?
