i use both manhunt.net and gaydar.au.com

gaydar get you to create a commercial account, but have no issue in you hitting guys up, manhunt dont have a commercial account options (as far as i know) but if i see a guy i like, i chat initially with him about non porn stuff, then let him know i work in porn, and ask if he has any interest in being shot for our sites etc etc.

both sites work really well for me in australia.
