That is the norm, I suspect, Inshallah (obviously I mean the use of that word ironically, just to be clear)...

Or, at least, is the case in like... Probably the majority of "young bisexuals" and the like, lol...

There's a reason the "lesbian in college" stereotype exists, and is so prevalent, lol. It is very much at least partially based in fact, no matter how much the Alphabet Lobby might deny that fact, lol...

And I've met a couple of girls like you describe, so the anecdotal experience carries over, there, too, lol...
