I can offer:

http://www.RopeBoys.com
http://www.LassoBoys.com (comes with the singular version lassoboy.com)

Both domains are suitable to monetize on the current cowboy hype caused by that Brookback Mountain Gay Cowboy movie which grabbed some Oscars:

- the names are catchy and brandable
- ropes and lassos are terms tightly associated with the term cowboy
- Rope and lasso work as verbs, too: rope a boy, lasso a boy (thus also usable for gay dating)

And the names have a Bondage flavour which keeps them still attractive once the gay cowboy hype is past.
