This is a question which comes frequently with cyber dating.
Cyber dating has its set or unspoken rules and behaviors.
If you go for a first date with a guy you met online and notice that his profile is still posted and that he is still frequently online, don't worry about it.
It is perfectly okay.
The first few dates are a non committed stage.
It is okay for you and for him to keep your options open and to stay in touch with other potential dates.
It is perfectly okay to date casually more than one person.
This is what happens with modern dating events like speed dating.
It is okay and it is fun!
Competition, openness and non exclusivity are part of the game.
Don't be offended or worried about it.
Simply make sure you are at your best.
