I married someone 16 years older than me and no, it did not work out. Thats not saying that it couldnt, but it didnt for me. I want to have, and to be a partner in a relationship, not just an anonymous caretaker. It ended when I found out that I couldnt even expect of him what I would of a friend. And no, it didnt start out that way.
I was 14, he was 21. Strange thing was I was more experienced than him. He was afraid to even touch me lest I get offended and scream statutory rape. In hindsight, I think he was doing the right thing, but it annoyed me at the time, so I broke up with him. He was one of the nicer guys I dated as a teenager; I kinda regret letting him go. C'est la vie.
No. I would only date someone close to my age.
