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*
