I've come to the conclusion that not every woman can and should do this. I figured out I'm one of the women who can't.
However, at one time, I had what I called a rotation. I always kept at least 3 men in the rotation. I would speak with them on the phone, go out with them, etc, but there was absolutely no sex with any of them and no kissing more than one of them at a time.
I only told the ones who could handle it about the rotation. Sometimes it's more trouble than its worth to spill all the beans but other times, the dude is cool with it for various reasons. For the most part though, I preferred that it remain a mystery. The fact that I constantly had some outing or something tipped most of them off that they weren't the only one.
I didn't spend time comparing and contrasting because I considered it a waste. The idea was for me to get out and meet/see people without any strings attached and with enough space to do whatever I wanted. I think if I had been looking for a relationship at the time, I would have been comparing for the sake of deciding who to promote and who to fire from the rotation.
Typically speaking, whomever asked first got the date UNLESS a guy I REALLY liked asked after a guy I didn't like as much, but regardless, they absolutely HAD to propose the date a minimum of 48 hours in advance. Otherwise, I would politely explain that I already had plans and suggest that he try again another day.
When their personalities were different, I didn't compare apples to oranges. Throughout the process, I knew exactly what I wanted so frankly, what they brought to the table was almost irrelevant if it wasn't in keeping with my desires. I think the key is to not get in too deep with more than one of them at a time, and when you get in deep with one, immediately dismiss the others, lest you be accused of playing games/lying/etc.
Juggling wasn't difficult...I don't think I even considered it juggling because there were only 3 in the rotation at a time. If someone new came along, I assessed whether to remove one guy and put the new guy in his place. Otherwise, I kept it moving. It was fun because I always had someone to chat with when I was sitting in traffic and I rarely spent nights at home on the weekends.
The drawback was that it didn't afford me the time to really focus on me the way I felt I needed to in order to open myself up for a relationship. At the end of the day, I felt that all of them were a distraction because had the "one" come along, I wouldn't have as much attention to give him. I've learned The Technique of the Love Affair and I get how to maintain my life with only one guy in it so I don't necessarily have to have multiple men around for the sake of maintaining a guy's interest.
So, I figured out that I'm simply not the type of woman who needs that much attention or who loathes being alone. At some point, I knew it would be more trouble than it was worth when they wanted to be exclusive or take it to the next level. I didn't want to be on a merry-go-round of shutting unqualified men down even though they were good enough to be in the rotation. Ultimately, I actually enjoy many aspects of being sinlge and unattached, and I'm enjoying using this time to continue exploring what makes me happy, growing closer to God, and developing myself as a woman in preparation for what the future holds.
BUT...I had fun while it lasted.
