Depends on the people. If one or the other is pretty shy? It may seem like a few are like the first date. Usually first dates are pretty enjoyable and it's time to get to know one another some. If a lot of time goes by in between dates? Then each one might feel like first dates. I would say that two or three could feel like first dates and that's fine. Just builds up your anticipation of more to come.
My friend told me, you can enjoy that first date anytime your mind connects as one. In other words, I think my friend was saying, it's all about the moves, both physical and mental :) Any way, that's what my friend said.
