If we accept the premise that no friendship builds beyond the first lay and friendship is a cornerstone of a long relationship. We are left with two choices.
1. Have sex right away and hope it works out. This is a shotgun type of approach where we get the intimacy we crave right away and avoid the anxiety of building a relationship which comes with the possibility that it ends before it begins.
This works once in a while and can increases your odds of more "dates" in the short term.
2. Wait till you know him better. To put it simply you want a man who wants to be with you no matter what you're doing. I call it filling in the other 23 hours. A man falls in love with being with you. This happens over time in the course of many days and different situations until your lives fit together.
This removes the awkwardness of waking up in the morning with someone you barely know and trying to put the pieces together.
In summary depending on your goals less can be more and this includes letting a guy sleep over without sex early on.
Whichever you choose make it work for you: do what feels good for you, and let me know how it's going.
