I had the "that's it?" problem after my first so I do believe my standards dropped as well. But, now that I'm beginning to get into the hunt for the lifelong mister, I'm setting my standards a little higher. My first and I are still best friends even after breaking up years and years ago, so I don't regret that one bit.
BTW great thread! It's nice to have a thread about sex that isn't so raunchy like some of the others
