oh, right - handjob would be good as i don't know of ANY handjob sites. and don't forget rimming, but that will be harder to shoot the closeups because of the guys' heads being in the way.

but my experience is if you don't know a niche, the content you shoot won't be right for it, and there are plenty of sites out there already that don't understand their niches.

so i still say shoot what you know!
