How frequent should i masturbate? single, nvr had sex, lose concentration due to erections, i do like 4 times on weekends, but feel weakness afterward

?: You don't need to masturbate - ever. There is no should. It is only if you want to or feel release from it. You are expending energy from the activity so of course you will feel tired briefly afterward. Losing concentration or being infatuated with it though is a sign of a more serious mental problem regarding sex. More less masturbation won't fix it. You should see a psychotherapist esp at 28.
