I don't think I'm all that in terms of looks, but eye of the beholder, whatever.
AM is definitely a different game. You have to invest a lot of time in closing the deal with anyone you meet there, and that's definitely work. If variety and convenience are your priorities, that's what TER and SA are for.
I found that the lengthy process of getting with someone via AM was an investment. By the time you wound up BCD, you knew them pretty well and had a pretty good idea of how to make them happy. Maybe that's the upside to it - by the time you get together, you actually like her, sort of like in real life.
I'm single, but the reason I was on AM was precisely to find women who wouldn't take up too much of my time and attention, while still having a lot to offer. I just mentally counted it up, and wound up with 17 partners via AM, and probably as many dates that one or the other of us walked away from for the usual variety of reasons. I don't think I ever had an AM date that wound up BCD on first meeting - patience is essential.
I also have a friend whom I met via AM - because we were both targeting similar women! One of the women I was seeing said, "This other guy was hitting on me and he told me stories of some of the other women he saw much like your stories - you may have been dining off the same buffet." I'm not with her any more, but I'm still friends with him.
So, you know, everyone's experience differs. Sorry it didn't work out for you, and I'm glad that SA is fruitful for you. Me too. Definitely having fun there.
