Just go to some bars with your gf together and ask around. Have a couple of brews, get to know the girls and sooner or later you'll meet someone or a few that may be interested. Most girls will probably know someone that likes girls or does the couple thing.
I've seen some of the girls get along better with the female than they do the male in the couple.
One thing though, whatever photo's you take, make sure you provide copies to all forum members as gratuity
