I'm curious to know how people here think about the question ... How many "serious" partners are workable? And by "serious," I mean deeply involved loving ("romantic") relationships that involve long-term commitment, akin to marriage (or inclusive of marriage).
I realize this question depends enormously on how much "free time" one has, which may be a vague concept (free time), so that's open to discussion as well.
Lately, I've been thinking that two is plenty, while three could--would likely-- push beyond my capacities. At the same time, perhaps three would be possible, as the upper limit, sometime well into the experience of having two such partners.
I could see myself having a larger chosen family, however. Cuddly, but not sexual friends. Committed, intimate companions who are not also lovers. In fact, I'd really like that!
