There's a part of me that's always wished to be female and still be into other girls; it'd be so much easier to find a kink-partner! There's always tons of us straight male 'lees XD Still, I wish you the best of luck!
On a constructive note: If you haven't yet, try FetLife (I heard they made it Invite-Only, but I don't know for sure - if needed, I've been on for years; PM me and I'll refer ya). During my years of searching, I've found many a "looking for F/F only"s in the tickling scene. I hope it helps! ^^~
