Oh you're not too young...it can happen in the mid-20s and early years of marriage.
There's a ton of sex at first, but even if the frequency dies down, it gets better quality-wise after the years go on.
Stick with it. Marriage is intended to be a lifelong commitment. To far too many people, they think of it otherwise when things get tough, or just change.
I know it's not easy right now, but it never will be.
