How are these guys walking?!

I’ve been wondering how are all these BL bottoms walking around like nothing after some hours-long intense sex?

Sometimes I’ll sleep wrong, or cough the wrong way or sit funny and cause my lower back to hurt and it’s uncomfortable and sometimes I can barely stand, yet these characters talk about how much it hurts, then next thing you know they’re freaking running like it’s nothing.

Their resilience amazes me.
