How to get him to want to cuddle??

I know it's SO typical that girls get all lovey dovey and cuddley after sex, and guys are quite the opposite, but I really wish my bf would want to be affectionate and cuddle after sex.

I just want to hold each other and be close, we just shared something really intimate and special, but he usually wants space and to just fall asleep, and sometimes he's quite terse with his wording when he's cleaning up (probably because he's tired and it's late at night and sex makes him more tired, he's not meaning to be terse, he just kind of sounds like a confused zombie).

How do I get him to be more affectionate after we have sex? It's kinda depleting sometimes that he's not :/
