Question
The Halacha states that there is a mitzvah to honor first born brothers. My question is, does this apply if the oldest brother is adopted? What if the oldest brother who is adopted is a first born from his mother? What if there is a brother who is a first born from his mother but not the oldest brother Among the family, do you have to honor both him and the biological oldest brother?

Question
Is it problematic at all in Halacha with Jews reciting yizkor prayers for non observant parents who have died? Or no, even if they weren’t particularly observant or religious is it still preferable to say after they’ve passed?

Question
my question relates to oral sex on a man. I understand that there is debate over this being an accepted activity between a married couple. But if it was accepted, what would be the appropriate choice be once the man has finished ie: is it considered acceptable to swallow? Is there an argument that doing so is cannibalism? If the source is a Jewish man, is there an issue with kashrut law? I guess, to sum up, what’s the deal with giving oral sex to a man?
