Yess, you can but masturbation has to be in limits... For night fall let me guide you.. Night falls are natural phenomena. It mostly happens to youngsters... but sometimes to adults also. But when we start having excessive night falls i.e. more than 5-7 times a month then sometimes there starts some problems like we start feeling weakness, tiredness, laziness, fatigue, body pains, constipation, erectile dysfunction, loss of libido, etc. But sometimes all these problems may happen because of some other medical problems and not necessarily because of excessive nightfall falls. Try to avoid non-veg, spicy Fried chilly food. Do not watch porn videos... whatsapps… Messages… and other such porn materials. Take good healthy diet, do exercise & yoga daily. Preferably, Pranayam, Meditation, vajroli mudra and Ashwini mudra, Read religious books or watch religious materials before going to sleep. Keep stomach clean & avoid Constipation, I am suggesting you some ayurvedic medicines. Take satavaryadi churan one teaspoon in the morning. Take chandanadi vati one in the morning and one in the night. And take tablet brihat bangeshwar ras. One in the morning and one in the night after food.
