Not having a filled out profile can warrant non-responsiveness. For me, I don't respond to men who don't have a filled out profile. I get too many messages and having a filled out profile helps to weed through some of the communication. It helps me to make a decision if there is potential match. If I see a filled out profile and think there may be a potential match, then I'll respond to a nice message. But I would never expect a man to take an hour or so for the first message. But that is totally up to you. I'm not saying we cherish just "hi" either. Good luck and I am glad you reached out.

Also, if you and the woman are very far away, that may be reason.
