If both of you had a good time, does that mean you'd like to go out with him again? If so, why not ask him? The worst that can happen is that he says no and then you don't have to spend any more time wondering what to do about the situation, right?
**Of course, this dismisses that the worst that could happen is actually that he says yes and the two of you have some kind of relationship that somehow has terrible unforeseen consequences (for ex. you two have a child who grows up to commit the worst genocide the world has ever seen). But, since this risk is inherent to going out with any guy ever, it cannot be applied to deciding whether to go out with individual men. More applicable is the possibility that he is an axe murder or some other sinister character, which I am also dismissing because it also applies equally to all men unless he has give you a reason to believe that he is more likely to be dangerous, in which case it would be a valid consideration. I'm assuming that he has not.
