For a number of creepy reasons, I advise making sure the first several dates are in a public place. Unless you have known the person and invited them to your place as a function of knowing them before, that sets off a creeper vibe. And you wouldn't believe the stuff that goes on if you haven't experienced it. For instance, the woman I am married to dated this dude before we were married, and they were kind of on again off again. I knew her during this period. She broke up with him, and he asked her if they could just go out one more time as a way to break it off cordially.
And proceeded to lock her in his van, take her to a place that he paid a friend of his to make available to him (a lake cottage), took away her clothes, and while he didn't sexually molest her (beyond taking her clothes) he demanded that she couldn't leave until she admitted their love was forever and took him back.
I led a posse of my friends to find the place, not because I arranged things in advance like abge suggests but because I knew when I couldn't reach her that night that something was wrong. The problem comes in that she had just recently moved to Lansing (where I lived) from near Detroit, so none of us were familiar with the area or people involved. I remembered enough from talking to her that I was able to track it down successfully enough (a different friend of hers went to check it himself thinking I might be creepy, as I came across him by knowing where she used to work and knowing the names of a few people there from old work stories).
This might be one of the biggest reasons she puts up with my shit nowadays.
