Awwh that's rough, a full group?  Bummer.  I'll be honest though, some lesbians aren't okay with mtf women, just like a cis woman may not be comfortable with a ftm man.  Sorry for the darker thought but it happens unfortunately.
Hmm, I can't say I recall Baltimore as being a particularly LGBT friendly place.  If you're in a good position overall there's places north and south of Baltimore that might be worth the trip honestly.  I live not too far from there and I know what's around.  Richmond is a good place last time I was there.  Some place in Massachusetts I think too...  But all of these are travel and may not suit your options.  Just a thought.
I've actually come across the best people on non-dating sites; actually ones that at hardly social media at all.  Maybe that's just my luck of the draw, but its true.
I used to be around about 18 months ago but I don't recall much about you Suzi 

  Sorry!!  Many *hugs*
