I'm experiencing similar (problems?). At first, finasteride made me super horny, then my libido dipped, and now in the past few days I have been excessively horny again. I am hoping it stays this way. One thing I noticed was that at one point I had missed 2 days in a row of finasteride, and that is when my libido was at its lowest. It makes me believe that for at least some people, the libido problems have more to do with the hormonal imbalance, as your body adjusts between having and not having DHT, not from a mere lack of it. Meaning that for some propecia users, once your body gets used to not having DHT, the side effects will go away. I can only advise to keep using finasteride as consistently as possible. I'm currently on 1.25mg proscar, up from 0.5mg every second day. I gradually increased my dosage over-time to increase efficacy while giving my body adequate time to adjust to each increase in dose. Seems to be working fine. Close to 4 months on finasteride.
