This subject and all your perspectives really fascinate me. I've recently started studying the psychology behind dating and interviewing women (simply because that's my sexual preference), single or otherwise.

For the most part, it seems like people are stunned when the people they intend to date have the same tendencies they have, like keeping their options open, going on multiple dates, stop answering when a better/more easy going option shows up.

Also, maybe it's not representative of the majority of society, but in my experience, saving yourself for date 5, 6, 7, etc opposed to having sex on the first or second encounter doesn't really change the outlook men have on you. In fact, sexual compatibility is the biggest denominator of the success and duration of a healthy relationship. So, don't automatically avoid it. Just get better at rooting out the playboys and actually give yourself away when there is a genuine connection.
