The pleasant pain that follows an episode of hard sex.
Jim and Kathy did it so hard that they broke the bed. The next morning they both had a sexache.

when you crave so deeply a sexual encounter with a romantic partner or love of your life.
I craved him so deeply, it was a physical ache..a sex ache.
