It has been 22 years of marriage and I need to have ghusl-e -janabat everyday for 2-3 times daily. Even I used to try to take bath but keeping my hair wet all day long is not possible at all. Sometimes I very enthusiastically used do it for 2-3 days but then I have severe migraine and thus stop. I am guilty of not saying my prayers regularly, which I used to before marriage. Having a relationship is the only thing which hinders me. Please tell me if there is any solution. I am helpless but hopeful as well that if my desire is to do sajda Allah will help me. I asked it from a couple of sources and they say that there is no way and I have to take whole ghusl whatever the case and our deen is not easy. I cant do it every day especially in winters.
It is better to do Ghusl after every intimacy. However, it is permissible to suffice with one Ghusl but better to wash your private part after every intimacy during the night. With regards to during the day as there is Salah in between then it is Fard to do Ghusl.
عن أنس رضي الله تعالي عنه أن النبي صلي الله عليه وسلم كان يطوف علي نسائه بغسل واحد

ولابأس للجنب أن ينام ويعاودأهله قبل أن يتوضأ وان توضأفحسن
