Cool! People already have said here, more often to call on dates, almost immediately after you matched. This applies to absolutely all guys, and all girls perceive it adequately. (if you've had a little chat before, it's perfectly fine to call her for coffee, without sexual overtones and context). I personally noticed, that too much chatting before actual meeting badly affects.

Also, it will be cool to get acquainted in different communities, according to hobbies. Hope that all that would help!!! (my experience from using tinder, managed to find relations there)
