I, to a certain extent, belive that age is nothing but a number. But I must ask...how much older is this guy? Not passing any judgement here but when I hear of young girls dating guys that are WAY older then them all I can think is "if he can't get a girl his own age, there must be something wrong with him." Just my opinion though. As long as you are happy and he treats you right, that's all that matters.
