Obviously the older you get, the less it matters.

You can't say X number of years and have it mean anything. If anything, it should be a percentage to matter, if that's what matters to you.

Age shouldn't matter if love's involved (as long as it's legal). Very large age differences might not (and probably won't) necessarily work out for a real and serious LTR, but many people (male and female) are "into" younger or older on a pure sexual and/or psychological-need basis.

Personally, I'm usually more attracted to those younger; and, one of my friends is the opposite. And we can't see each other's point of view at all! lol But it's all good and shouldn't make a difference.
