Hi Welcome to Healthcaremagic.com,
is acceptable. But realise too much is not good. Weekly 3 times per week is OK. But maintain a gap of 1-2 days if you are tired and exhausted.
It is a way to release fantasises. You can use the masturbation for imagining , enhancing you sexual fantasises. Actually it must improve your desires not kill your desires.
Good sleep, good rest and good diet are necessary for gaining energy.
