I have tried both, so I can compare: Iranian guys tend to have dicks that are short but fat, usually around 5 inches erect. Arab guys are generally very long but have average thickness. Both have nice looking dark brown circumcised dicks. The Arabs all had tight circumcisions. When I gave them handjobs, there was almost no mobility in the skin on their shaft, whereas the Iranians all had loose circumcisions and could pull the skin on the shaft a bit over the edge of the head. The Arabs I slept with lasted a long time. They could go for a whole hour before ejaculating, whereas the Iranian guys lasted less than 10 minutes on average. Also, Arab guys tend to stay hard for a few minutes after they cum, whereas the Iranians went soft right after they came. Generally Arabs are very aggressive and rough in bed, whereas the Iranian guys tended to be more gentle and were more into slow romantic sex, as opposed to wild fucking, which Arab guys seem to enjoy. Anyone else had similar findings?
