I guess you are still doing something with your partner

Use viagra next time

At that point just give up and go to sleep...

Sex can take a lot out of you...in more ways than one...

You need to go and find the big silver key, obviously you both are not wound up enough.

Well since you did it together, maybe it could be something you laugh about together and try it again when you're not too sleepy c:

You guys are boring

It's probably best to stop until you're somewhat rested. But after you do it again, you will sleep more ;)

I've got just the cure! Just last night I was thinking about cadavers and couldn't sleep the whole night! So I did some meditation and some research in the mean time. I feel great now.

Maybe if you're both tired and want sex next time try a quickie?
