Round II is always enjoyable. Then again, what round isn't enjoyable. Some of it depends on the time round 1 starts. Lately nothing starts before 11:30 - 12 midnight. At that hour, 1 round is all that is going to happen before sleep wins out over hornyness.

I also enjoy round 1 before going out for the evening and round 2 upon return.

Thanksgiving dinner for 17. I would ask for the Round II sex 'Thanks' for the next day - after a night of sleep.
