It has done both for me. It can be invigorating recharging. Like joy and exertion are enough juice to drive one through tasks and functions. Float or fly.
I also love cuddling and sleep. The intimacy of being wrapped in another. The relaxation of tensions I hadn’t realized was present. A melting.
As far as continued pleasure I can be impulsive. I usually like three consecutive acts of congress. Each building and riding the wave of the other. But sometimes tiredness or time or just the moment calls for a somewhat haphazard quickie.
