Younger days in 20s and 30s, could easily restart engine within 5 minutes of shooting. On its own, no stimulation needed. In early 40s, need to rest about 30-60 minutes. Then can re-started on its own. In late 40s, same rest time required but need oral stimulation from the partner to restart engine. The better the skills, the faster the engine can be restarted. Age plays a very important part. Older people need more tactile stimulation. Young men can get started very easily just by visual stimulation.
