While it is obviously okay to be tired, maybe don’t promise what you won’t keep. It can disappoint your partner and if it happens often enough, these promise might turn them off as they remember the disappointment and eventually, possibly make your partner feel undesired. I mean it puts words and actions in contrast and once words seem meaningless, actions become everything and if you were excited to mess up around, would you be sleeping? So your actions wouldn’t communicate desire, but rather the opposite.

So while sleeping is totally okay, if you realise that you often promise a lot to then fall asleep… maybe stop promising and start looking for opportunities to show your desire when you aren’t tired and in the mood.
