Girls, Why are girls so comfortable with kissing and cuddling with other girls?

Despite claiming to be totally straight, most girls and women are very comfortable with kissing and even cuddling/ touching each other's bodies including the boobs?
Why so?
Because girls have really attractive body, even straight girls can't resist it
Because most of the girls are at least bi-curious
Because most of them are bi-sexual but hide it from the society
Because it doesn't do anything sexually to them. It's just pure sex-less and romance-less act
It is not true. I don't want to kiss , cuddle or touch another woman's body
