Most Helpful Guy
If you aren't attracted you aren't attracted, but don't confuse that with chemistry. Chemistry sometimes takes time to build. In first dates, there can sometimes be nerves involved that prevent chemistry from everyone involved. Some men and women like to take things slower than you might expect.
Sparks happen when you least expect it and don't when you are looking for it and expect it to happen right away. I have a feeling so many men and women miss out on something good when they put so much pressure on a single encounter.
Of course if things feel completely off then it could be a compatibility issue, but I think good chemistry develops over time.
