Men please answer this?

Honest Fool has pretty much got this pegged. Inter-office romances are generally frowned upon, if not completely banned. To get involved with him could get you fired, and if he's married or in a relationship, that's a whole 'nother kind of trouble you'd be asking for. However, if there are no such policies or restrictions placed upon you, it's all up to you. He sounds interested in you, and since he's taking such a direct approach, you may just have to sit back and gauge his responses. He may just be trying to befriend a coworker.
