Actually meeting the person you are talking to is one of the most important steps to online dating.
That sounds amusing but many online daters dwell on internet communication overly long. They wanted me to get the show on the road and they were right to feel that way.
You want to talk with them and if things go well meet them.
If this happens to you, wait a few days (continuing the email conversations) and then ask again.
Unless a good reason is give for not meeting, I would not ask more than three times – there are some people out there who are looking to make online friends or live fantasies out in their head without any intention of actually meeting.
I found that people will not be offended if you suggest a first date before they are ready.
In my experience, the other person would offer an excuse but continue communicating.
I never went for phone conversations as a stepping stone from internet communication to meeting.
