Dude you should say to young for a start and not small. My mind went straight in the gutter. Why is it important that the woman is older than you? I have been in younger male relationships and was married for a long time to a man younger than me. But I have decided I need to move on because boy aren't my thing any more. But I am sure if you gave it time someone will want to have a stud like you. So just be patient and don't push yourself be a gentleman and you will find someone.
Good luck
