Back to mono... gamy... Is it possible?

Ok, so I've never really been in an open relationship, much less a polyamorous one - in fact, I think I might be too jealous to do it; however, with my ex we had an arrangement where we would admit a third as long as it was the two of us together.

Still, after we broke up, I dated some people casually and enjoyed the pleasures of being able to do whatever I wanted - this led me to the idea that, perhaps, I was ready to try a more modern kind of lifestyle. Would it be possible for me to actually separate the sexual and affective components of relationships?

Well, I still don't know the answer to that question. Nevertheless, recently I was presented with a situation which would mean going back to being completely monogamous... So... Ouch...

I mean, taking the step from being faithful to one person to fooling around with other people is not that hard... But going back?

As I was pondering this question, I, of course, started listing the pros and cons of the situation. On the one hand, I believe it really promotes a deeper connection between the two people, there is more of a romantic, idealistic tint to the relationship and it is way safer. On the other hand, you only have sex with one person... Now, don't get me wrong, I think that growing to love someone and enjoying intimacy with them is an experience that (takes time, obviously and) can't be beaten; but I also think it's true that we humans are not built to be monogamous. In the days when sex was all about reproduction and making little heirs, of course it was vital to make sure the baby was your own, and yet I think that there is way more to it.

Another factor that I think is very important to consider is questioning this custom; asking yourself if you want to be monogamous because YOU really want it or if it is because that is the way you were brought up.

Personally, I went through this process and discovered that, while it is mostly because that's what my parents (and the media) taught me, I still think there is some value to that commitment.

I am, evidently, still considering the option... In fact I am reading a book on modern relationships which I really want to talk about here... I hope I get a chance to do it soon.

So, what do you think? Can one be monogamous after trying the alternatives?
