Why does the age difference bother him?

Anonymous
So my best friend and I are obviously attracted to each other. We are very close, and we get a long great. Our personalities really click, and we trust each other fully. We tell each other things that we have told no one else, etc.

I am older than him, and do not take me for a creeper. We both are strong Christians, and I would never, ever do anything to jeopardize our friendship nor would I ever try anything inappropriate. He is 15, soon to be turning 16, and I just turned 19 a month ago.

Well, I finally decided to tell him that I felt our friendship couldn't continue honestly unless I told him my true feelings for him, in which I did so. I told him that I liked him slightly more than a friend. With which he responded saying that he already knew, and that "if you weren't older, then yeah. ha." and I told him I understood. Then he apologized for "not exactly feeling the same way, but mainly because of the age difference."

When he said this, it did confuse me. Did he mean that he did somewhat like me? Or that he would if I were not older?

Are most guys bothered by a girl being older in a relationship?

Honest answers please!
