Medication Situation

I have been humming along quite well with no PMO for a while, and then about three months ago I tapered off from Lexapro after taking it for 10 years. In these three months, I have felt absolutely fantastic and I knew that I did not need the medicine anymore. It has caused me to be much more sensitive and aware of my emotions Without everything being numbed to a degree. However, it has made me also extremely horny and sensitive to an erection and I have fallen back into PMO. I am in my 60s and I am divorced and I’m not sexually active and I feel like I’m 25 years old in that department. There’s some situation that might be great but for me it’s not and I would like some advice to help me get back on track.
