Festerbation

Festerbation is the act of choosing to wallow in escalating sexually longing without any reprieve or sexual release. It is physiologically unhealthy in that it increases stress levels in the individual.

Jill was rejected by Jack. Instead of a revenge fling, Jill fixated miserably on all the great sex they used to have, and "festerbated" herself into a migraine. The migraine was due to extreme "festerbation".
