I've been through phases of wanting to juggle multiple people (for the ego boost, I admit). I know that people like me--I just had to put in effort to maintain them.

What always ended up happening during these "phases" was that I'd get so overwhelmed by the level of energy and time that people require to build a relationship, I'd drop the ball on it completely. I'd always end up putting most of my time towards one person that I liked most anyway, and the rest would have a negative view of my lack of effort and I started to get a reputation for being manipulative or uninterested.

My view of meaningful sex is the same--it requires too much energy and time from me that inevitably leads to nothing. Not even physical pleasure. So there is no point or value in it other than an illusion of intimacy.
