Well that's all that matters.

Some people are comfortable dating someone who is older/younger. Others are not.

Me, personally, I don't want to date someone more than 5 years older or 10 years younger. I actually prefer younger as these guys aren't "settled down" and set in their ways yet. I'm in a similar place in life to them vs guys my own age since I've had some setbacks in life and am still in school, working on my education, etc. Guys my own age or older tend to already have kids (and I don't want to be low on the priority list), many are divorced, etc.
