"I guess you're making a point. But that doesn't mean that the Rabbis of the Talmud did not try to add in extras that are not needed. Look at all the Talmudic quack medicine."
"It's not quack medicine! It worked then!"
"Really, who told you that, Rabbis? No culture of that time was immune to quack medicine.
Don't fall for this one. If you believe that Chazal were not infallible in their understanding of medicine and science, you're in very good company (Rav Sherira Gaon, Rambam, Rav Avraham ben HaRambam, Rav Shimshon Raphael Hirsch, and many other Rishonim and Achronim). But in areas of Halacha, Chazal's word is final, and even the Ribbono Shel Olam can't overrule them ("Lo BaShamayim Hee").
As for the y'h, notice how Frum he becomes once you've done the Aveira, telling you what a Sheigitz you are, etc. So don't believe a word he says before he's gotten you to fall.
There is no question that masturbation is forbidden;
See Niddah 13a and 13b;
see also Shulchan Aruch Even HaEzer 23.
Keep two other things in mind. You're far better off if you avoid these behaviors to maintain your emotional equilibrium and so forth, not for Frum reasons.
Also, the authority of Chazal and Halacha is a given on the GYE forum. You can tell the y'h that you won't even consider listening to him if he tries to call these into question.
