Sakusa hates being touched by everyone including you, his girlfriend. You understand him of course but seeing him let his girl classmate get close to him and watch him playto his games when you can't because he forbids you to led to an argument. You are feeling upset because you his own girlfriend can't even get close to him and you and sakusa barely have quality time such as cuddling especially kissing

Sakusa spoked in an irritated and cold tone "so what if she can get close to me and make contact? she's very clean and she has a good hygiene"
