Where'd you get the photo of Steve Pavlina?
He's the ugly dude who had the balls to tell his wife years into their marriage that if she didn't agree to bring other women into his marriage then, well, he was going to anyway.
I hope she took him for every fake "million" he always claims to be making as part of his "success teaching."
There's nothing wrong with having multiple partners as long as both partners are in on it from the beginning. Don't be changing your mind years into something and then try to shift the rules around.
If you're not capable of monogamy, you already know this about yourself, so at least be up front with the women in your life.
I think it's also helpful to spend some time not dating at all so you can figure out just what place, if any, a woman might have in your life.
If you're a lot happier without dealing with a woman day to day then just get fuck buddies and you'll be fine.
If you like to have a combo friendship/sex partner/house mate then you're more on a track to be a longterm partner to the right woman.
It will take you a while to find that woman, though.
Women do NOT reveal their true selves until a long time into a relationship, I've found.
Took me a few tries before I was lucky enough to meet the Mrs.
We have a cool back and forth humor/flirtation/friendship thing going on all the time that just makes life a lot more hot and fun. Everything on top of that is a bonus.
I didn't have that with other women; they didn't seem capable of it.
