I think the use of LGF (little girl friend) is not really accurate - just wishful thinking. I don't know why people keep using that term here.

I definitely agree! I've been wondering at it too. Okay, Azure said he meant "Little Girl, Friend", but many others still keep using "Little Girlfriend" to describe their little friends.

I think that if someone is your GF, you and she must have confessed your romantic love to one another.

Secondly: in my youth there was this young woman X who I had fallen in love with and who also liked me quite a lot, though she was not sure about her feelings. We never went to bed, because X was religious. Now, did I call her my girlfriend? No. We never had sex, so she was not my girlfriend. I had some adult GFs when I was younger, girlfriends who gave pussy to me, but she was not one of them.

Yes, in certain circumstances lovers can be lovers even without sex: two kids who love one another, or maybe sometimes an adult and a child. And even two adults in some special circumstances.

I think "LGF" is used too lightly here. I have told that I've had a crush for a certain girl and we have spent time together, but it would feel preposterous, even absurd and perverse (in this case) to call her my GF.
