Love is moe important than sex. But unless there is some underlying problem, love should include sex.
Eg. As a couple ages, their sex lives ebb & flow at differing rates. If you love your partner you should recognize when their drive is higher than yours & do things to accomodate. I don't mean put out every night, just to make him happy, but push yourself to be more helpful. sometimes when you are only helping out, it gets you in the mood too. Plus when you are sharing an encounter, it's still an intimate bonding experience.
All you younguns won't know WTF I'm talking about, but remember this as you age.
