Hi Roman,
It’s normally a good idea to at least give it a handful of conversations before you ask someone out.
You don’t want to appear to be too eager by asking the person out right away, as though you are in frenzied competition with other guys on the dating app. Get to know them a little bit, see if there is conversational chemistry.
A handful of consistent and robust conversations should be enough for the both of you to know whether there is at least an initial connection. From this point on, you can ask the person out.
