Suetonius. . . just possibly, guys on RJ, with all its sexy pics, may not be very representative of gaylife in general.
THIS! I tend to think that many of the things seen as specifically "gay" (clubs, websites, etc.) tend to cater more towards those that are single. There are obviously exceptions, of course. But I suspect that people who enter an LTR (especially if it is one they expect to make a life-partnership out of) are less likely to show up in bars or online etc. where there is an emphasis on dating to one degree or another.
Also, I am single. I'd like a relationship, but I'm not willing to settle in order to get one.
