Seems to me by now you should have had "some" experience. Anyways, a lot depends upon where you live. Location, location, location. There are some locations where it's just very difficult to find guys who want to get off with other guys, and if you're after guys in the top percentile, dick-wise, you're basically expecting an act of god. So, I will give you a hint. Go to a city big enough to have a leather bar, find it, and then some night step inside
One additional hint it seems like guys with big dicks tend to walk a certain way. Good luck to you!!!
