So, realistically I'm managing four or five plates. Two that I spin more frequently than the others. All plates i keep indirectly aware that I'm not monogamous without saying who or how many. These are the only two I sleep with.

The thing I've found I do and I don't know if it's good or bad but i think I lean toward it being good: I leave my phone out and face up, on silent when I'm with a girl. It's not necessarily in front of me. More like, on a counter or something. I do have a lock code on it. My phone lights up when I get a message/call. I always put a photo with the girl in my phone. (This helps me keep it straight sometimes. Less error in sending the wrong message to the wrong girl.) My plate #1 saw #2 calling. She said my girlfriends won't even leave me alone when they know I'm with her. #2 did know I'm with #1.

FYI the number references are no reflection of my preference of the two.

So, the point being this drove #1 crazy and she latched on much harder than she'd previously been.

I feel this validated #1 by showing I'm only interested in spending time with her at the moment by showing I'm ignoring #2. Yet, it also stimulates her imagination/insecurity in knowing another girl was seeking my attention. Additionally, any time I don't respond to her she'll feel this same tension by remembering me ignoring my phone while with her.

What feedback do you have on these tactics? Are they good/bad? Any changes you might recommend? What do you do?
