it's awkward because even though you're not looking to start a conversation, you feel like it's expected.
how about not trying to expect a conversation? you can smile, roll over and take a nap. or you can spoon. or you can politely excuse yourself for a glass of water and a trip to the toilet (to prevent bladder infections). there are plenty of other perfectly natural things you could do with the next twenty minutes after you have sex.
