Am I the only one who

Am I the only one who after sex(only if I orgasm) then after that for the next day I will not be “lovey dovey” with my bf? I stop flirting and get really easily annoyed... the better the sex the more I need space the next day? Haha.

I feel so strange since I’ve heard an orgasm should make you feel happy... I feel the next day need to just be me.. alone...! After some days I will get flirty again and stuff.
