As long as they are neutered I don't think the sex is a big deal.
we try to have playroom time about 9pm, so they will wake up and run and play.
to early and they could still be sleepy. I try to have a treat and something for them to explore so they stay awake. we have little kids toys, plastic boat, mailbox, etc.
But even with all that some of the glider just go back to sleep and are NOT interested in playtime.
