Hello CyberSan,
SEXMoney.com has a few pissing sites, that convert very well. The sites are in multiple languages, thus allowing you to harness all of your traffic, not just US. We pay out in FULL on ALL Exits and ALL Payment Methods.
As far as FHG, I do not have any at the moment for this niche, however, I would be glad to provide the hosting of any galleries you make for our sites on our servers... I just got some real nice not over-used pissing sets for our webmasters.
Check out:

In addition, if you only want a site for English speaking surfers we have
http://www.warmpee.com
I look forward to chatting...
Warm regards,
