It all depends on the persons involved. I knew my husband for about 3 months before we started dating, and 19 days into our relationship we had sex. Some people think that was too soon, but we were both ready for it. Now we've been together 3 years and are still very happy.
A married couple we are friends with had sex on their first date. A friend a mine has been with her guy at least over a year (not sure how long exactly) and they still haven't had sex because she's not ready to lose her virginity (he's not a virgin, he actually has kids).

No. I feel the same about you, need to know them enough to know at least they aren't psycho or something. Some people just really click right away and they like sex. No right or wrong, just what works for them.
