Welcome to SR unda, I totally concur with what freya said. Look for some one who has solid sobriety, has taken the steps with a sponsor them selfs, someone who has what you want & you are pretty certain there will be no attraction in either direction.
BTW I am a straight guy and I will confess that in my younger days I did have a "fascination" with and an attraction to femme lesbians so keep that in mind when choosing a sponsor.
AA is imho an awesome program that works for many people that is full of people not all of whom are awesome! LOL
