Hello and welcome to HCM.
As an
Urologist, i can fully understand your
anxiety.
It's a normal habit among males in your age group, to masturbate regularly.
Feeling of weakness after
masturbation is more a psychological problem.
Regular exercise and healthy timely meals will get rid of it.
Pimples on your face, is due to release of male hormones,at your age.
Again nothing to worry about.Wash your face regularly with warm water.
Avoid oily and fried foods.Take more of green vegetables and fresh fruits.
Gradually the pimples also will disappear. Don't stop exercising.
If you've any other doubts, send them as a direct question to me.
Dr.Matthew J. Mangat.
