hi, arshad.. i have understood your concern.. the masturbation is not a bad habit and it does not cause weakness..keep this in mind always.. the weakness is because of your worries about your sexual problems and it is a vicious cycle, more u worry there is more weakness and decrease libido, which will finally increase your worries.. so try to control your worries and thoughts. if u are not able to control this then identify yourself that whether u have depression or not because depression also causes loss of libido.. go for regular exercises, yoga, meditation, participate in your hobbies.. u can also take medication like: tablet, wellbutrin xl 150 mg once a day in morning after breakfast u shud increase the dose after 10 days to 300 mg once in the morning..[it is brand name of bupropion, which is a NDRI antidepressant, but here it will increase your libido particularly, thats why i ve prescribed..] i hope u ll find this advice helpful..best luck arshad...
