I been told that after junub one should need to have bath/gusul before having food or to pray. Although one can have food or do whatever they want but it is considered makruh and is believed that blessing from home stop coming.
If that is true then every time a couple became intimate and in state of junub, it would mean to bath every time and while some might live with families or with relatives, it does get noted of why someone is showering couple of times.
My question is, that is it true that eating food or prayer become makruh if you do not have shower after junub?
Reference will be appreciated.
