Absolutely. A few studies indicated that it may even help prevent prostate cancer in older men. Most experts on sex pretty much agree with the above about frequency and not abusing/becoming addicted.

It's especially important for men without partners. That sense of release is pretty helpful in relieving tension, sexual and otherwise.

I doubt there is a guy on the planet who doesn't do it from time to time. I personally have a pretty healthy libido even at 48, and, well, I usually do it 3-4-5 times a week. I got no problem admitting that, although there was a time I would have been deathly ashamed to even talk about the subject. My T asked me if I did it, I did NOT answer that one, because she is a woman and I was embarrassed. I don't mind talking to the guys about it, although it is still touchy.

I know some religions don't approve -- that is kind of old thinking in some ways, back to the era when masturbation was considered taboo, even harmful - "you'll go blind" etc. Have to respect that, but the guilt trip, as with the OP, is psychologically not a good thing. Makes them ashamed of satisfying a basic biological urge.

I consider myself a pretty normal hetero male. Started at puberty, around 14, and I still do it, even when I have been with women. It's especially gratifying if they will do it to you, exciting. I think it is healthy, normal, and is a safe release for those not in committed relationships. Helps with maintaining function as we age, can be used as a tool in some situations to deal with PE or other sexual issues that trouble guys. Final comment, I have very rarely watched porn, I find it's not necessary for me, I fantasize about past and hopefully future situations.

Please, OP, don't feel guilty, you are NOT being punished, by God or anyone else. Masturbation is common among higher animals, primates especially. It is just biology and evolution at play.
