Ok guys, I need some advice.

Because of what I've learned from this subreddit I'm in a position I've never been in before. I used to be lucky if I could even get one girl to like me, but no more.

Currently I have 3 different FWBs. Each one I like for a different reason. One is wild and adventurous, she has blue hair and is the youngest of the pack (18)- let's call her Skittles. The other one I share literally everything in common with. Our conversations go on for hours and I feel completely comfortable around her. We both are musicians and bond through jamming. She is perfect in all ways, except she's fat (23)- let's call her Chubs. The last one is exotic. She is a muslim (I have a thing for monotheism, don't ask). Extremely faithful and possessive and by far the most attractive of the group, yet conservative. (20)- let's call her Allah Akbar.

I've been dating and messing around with each of them, the last month has been great.

Here's my problem. The way things are going I'm very sure that within the next week each of them are going to want to make things "exclusive." None of them know about each other, yet. I'm also scared, because Allah Akbar is the only one I'm really interested in, and I can see myself weakening for her and giving in. She plays hard to get sometimes and it drives me absolutely insane. Ideally, I would continue to be fucking each of them, but at the same time I can't lie and cheat on all of them. Things would just get nasty and I don't want drama.

When they ask me "Am I your girlfriend?" What do I say? How do I make them into plates and get them fighting for my love, because I like each of them in their own way. What if they say they'll leave unless I become exclusive? Do I drop skittles and chubs for Allah Akbar because she's the hottest? Or do I maintain frame and hopefully make them jealous?
