For Androgenetic alopecia, Dute 0.5 helps reduce DHT levels, which is the main cause of hair thinning, so it is meant to slow hair loss and improve density, not worsen it when taken as prescribed. Being sexually active does not increase DHT in a way that worsens hair loss, so you do not need to stop normal sexual activity. Continue your treatment (including Morr F 5%) regularly, and follow up with your doctor, as results take a few months and need consistent use.
