No way!
On rare occasions similar to what @Arcosanti said, but extremely rarely.
Not nearly as much as I used to be. When I was younger, I thought in terms of "what I want in a man/relationship". Now, I find it's much more a case of "what I DON'T want". Probably why I will remain single. That is in no way meant to be taken as a complaint. All I mean is that having given the benefit of the doubt too many times has caused my heart to have built up a fairly significant layer of scar tissue. I doubt I'll be in another romantic relationship, and I'm no longer looking for it. I've got other stuff going on.
I love men, but chose to fly solo about 5 years ago, and have been quite happy so far. I live this way in part because I seem to be a magnet for really unhealthy men, but also because I require a great deal of time to myself (or in my head) have yet to meet a man who understands or respects this, and is secure enough to know this has nothing to do with how I feel about them.
