from my experience of one time encounter with a bunch (6) of lesbians:

they were too noisy; talked frank and straight, even came to us and admitted (actually they said themselves) that they were lesbians. dressed and combed like boys or hippies. it seemed that kissing, hugging in public for them is nothing

if you fear of them, avoid walking or roaming around in the late night. but they are also nice person like you and they don't force you to practice gay.
