text: what does everyone think about a 21 year old girl dating an 18 year old guy?   nothing wrong with that! i am 7 years my husband's senior! we are very happy and for the most part he looks older than me, until he shaves his beard off then he looks younger but b/c i like beards, he rarely ever shaves it off! also, my 19 year old son is seeing a 28 year old lass with a child and he seems to be pretty happy with her and her with him.
