Nivek saidHave had 6 LTRs in my life (lasting 6 months to 8 years) and each began with sex on the first date. In fact, all of the dates where we postponed sex, in the name of some sort of principal and propriety, never lasted.
Hmmmmm....6 LTRS? Apparently none of them worked out either, so I kind of doubt that having sex (or not having sex) on the first date was the ultimate determining factor. Personally, since the OP says he wants to create a relationship in general, I think holding out until at least the 2nd date sends a more positive message that meeting the guy isn't all about sex. If the other guy is interested, and attracted, holding off during that first encounter will likely only increase that attraction --- AND he'll respect you in the morning.
