dear doctor,
earlier i suffered from thyroid,due to which nephrotic syndrome appears (kidney disease)i had a lot of asteriods at that time (prescribed by my doctor)but now i am ok, its completely cured, later on i analysed that i am facing problem in my erection during intercorse,the erection is very less, i cant even insert it in the female vegiana,i feel masturbation ,i do enjoy masturbating,but now its not that hard what it was before the disease,is it because of the nephrotic syndrome or thyroid ?,is it 100% cureable ?,what are the tests which are required ?,do i have to take the asteroids again for this sexual problem ?
