His touch always lights a spark somewhere deep inside. I wouldn’t describe it as a butterfly as others do, or that might just be the beginning. The spark is like a longer lasting jolt of pure pleasure. You might need a rest after this type of feeling, especially if you’re lucky enough to have it more than once. It is described as a delight of good health, love, happiness and satisfaction. The twist is that most of the time it only lasts for a few years.
