Does a women who is immersing (counted 7 nkiyim etc.)
make a bracha even though she will not have relations (is it like netilas Yadim where you don'[t make a bracha if you aren’t going to eat bread)
How about if someone is SHechting A animal to throw to the dogs– does he make a bracha on the shchita??
Most opinions hold that since the actual immersion is a mitvah a brocho is recited even if no relations will occur. Also since physical contact is permitted that is also considered a mitzvah. Regarding shechitah there is a difference of opinion whether the shechitah itself is a mitzvah or it only a “hechsher mitzvah” i.e. a way that allows us to eat meat. So subsequently one who is shechting to throw to the dogs if a brocho is recited is dependent on the above dispute.
