ok . let me expand a bit -
Playmates - easiest to find imho, especially for a woman looking, as long as both go in knowing this is the score, most likely nobody will get hurt, (although VERY possible one or both of them can change and want more, very unlikely BOTH will)
LTR - Its not something that is negotiated, it cant be, Best possiblity is both go into it with the same mindset, that a LTR is something they both desire to find, and after getting to know each other a bit, are willing to explore THIS dynamic and see what the future holds. the heart is a finicky thing, nobody can really know when it will truly love another person, but you increase your odds of success dramatically when the other person is looking for the same thing you are.
And yes, sadly, the entire freaking planet seems hell bent on everything being disposable these days. People don't seem to want to put in the time, energy, effort, or unconditional acceptance that staying together demands. My marriage lasted 35 years, and ended out of a situation that could not or was not handled (you can find it in my blog if it helps)

But as I have continued my search, I am not looking for frills and thrills, getting between a womans legs for the mere sake of doing it is a game for boys, not men, imho, and I am far past being a boy. So my search is to find another now, a lover, best friend, and BDSM partner and I will not stop until I find it, or the good Lord decides it's time for me to go. I have learned in this BDSM Dynamic search however to be more open, that it is the PERSON I seek, and all that embodies her. Once who can touch my soul, and let me touch hers, one in whom I trust implicitly, and will return that trust. One who we will share all the deepest corners of our souls with each other, and know that is alright, that we each accept the other implicitly and unconditionally, and bond on a primal level few humans ever attain. And it's not about her age, her history, her past mistakes or successes - all that is now ignored, because I have finally learned that none of them truly matter. I could as easily find my missing half with a 20 year old ex convict former female escort as I could a 55 year old virgin.
It's not about the search you see, it's about being open and diligent enough to recognize her when I find her. But I do know to start the search, to have any chance of success, it required open and total honesty in what I seek.....
