That depends what you want to know about them that you already don't. Keep it simple as most guys are not into "deep".
ask him if he wants to hang out sometime. or ask him questions to get to know him better.
ask him how he aonestly feels about you
ask him what he likes to do for fun
Smile and ask him questions about himself . If he says anything, ask him more questions about what he said.
Try to ask questions that cant be answered with a yes or no. Ask him questions to find out what he DOES like talking about, or find out if he is just distracted doing five other things on his computer. From a guys point of view.....we will get annoyed if u ask to many questions........so either keep it simple or play hard to get and make him ask the questions
ask him his interests and small talk things
Ask him about something he loves
If you mean, why does the guy im dating never ask and questions about me, then I would say he might be a little uneasy about it. Maybe you should ask him why?? If he is not asking questions its because he is only interested in one thing. If he was looking for a long term relationship then he would attempt to ask questions.
Play hard to get!
only when they ask stupid questions
Well, he would normally ask you lots of questions and look at you. Well, he would normally ask you lots of questions and look at you.
U ask what he likes or what he does for fun stuff like that
