I much prefer longer term over one nighters. With a longer term situation, you get to know the guy, what he likes and doesn't like. Perhaps more importantly, he knows what I like and dislike. Also, to answer a previous post, my husband and I meet him socially first, explain what we are looking for and request an STD test. If he is agreeable and otherwise polite, considerate, intelligent and the like, we proceed, but nothing happens until he produces the test. This has worked very well for us and has led to some phenomenal situations!
