is that gay people have a really good sense of clothes. They are even more intelligent, intellectuals, very friendly, as compared to the straight guys. (Statistics and ratios).
About lesbians is different as one of them dresses up like guys and the other one is more inclined towards the feminine side.
I might be wrong as these are my personal observations. Not some facts in black and white,
Sadly I havent met any openly bisexual people
