Is it permitted for a male nowadays to shave his pubic hair for non-medical reasons? Perhaps this question could be phrased a different way: Assuming that the market for male-specific shaving products that are designed for body hair is an indication that it is currently normal for (non-Jewish) men to shave their body hair, would this in turn permit a Jew to shave his body hair since it has become a norm?
"Since it has become the norm" If jumping off a bridge is the norm, should I do it? Didn't Hashem forbid becoming like everyone else? When pagans shaved the corners of their beards Hashem forbade appearing like the rest.
"They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh." Lev 21:5
Who's going to see down there anyway? The hair is there for biological reasons, to pull heat away from the testicles so your seed doesn't die. If you aren't trying to make babies and the hair bothers you shave away. I would think your wife should have the final say on what appeals to her in that region (if you are married). But if your are shaven and it makes you lust all the more then you have done a disservice to your body. If people took the time to write out the Torah like David did then maybe there wouldn't be so much interest in what is down there and our relation to G-d and our fellow men might be better for it.
