I got Sildenafil (generic) otc in a pharmacy in Siem Reap. Cheap stuff from India, but it worked. 4x100 for 3$. They also had one pack for 4. 50 and one for 6$. It was possible to cut the pills in small pieces (since 100 mg is too much). I don't remember the name of the place, but it is close to Hotel Golden Orange. On the main street, same side of river).
Funny story in the store: First I asked for eye-drops for dry eyes, a local customer standing next to me looked at the product and said: "oh yes. That one is very good. Then I showed the clerk a paper note with "Sildenafil" on it, he went to get it. Then the same customer, a curious and friendly guy, looked at my note and said: "yes, they have some very good one here, and it is cheaper than in PP, and it works good", and he smiled. Very funny.
