On a related note, we found that early on in our exploration of this hobby, we had difficulty differentiating between meaningful sex (that which we shared together) and recreational sex. Consequently, we looked for a strong connection between us and both parts of another couple. Most new couples do this and while it does happen occasionally, it's a rare occurrence. That kind of expectation really limits the erotic possibilities for new couples. We've since refined our selection process to where we are pretty sure that when we meet a couple from one of the sites, they fit within our parameters and at least appear attractive to us both. The intangibles, personalities, bad breath, dumb as a box of rocks, etc will still end an evening quickly. However, since we decided that we're not looking for couples to introduce to our kids or to tour Europe with and recognizing that our goal is fun sex, we try to view a couple as "doable" or not. This has led us to more than a few erotic encounters and even a couple of lasting friendships. We tend to shy away from couples who say, "friends first". We both think that is a backwards approach if you're simply looking for fun sex and a little variety.
