On the other hand maybe this is the only way to do it effectively so that it reaches the maximum number of people. Isn’t that better than taking a chance on doing something that is forbidden? Or not doing something that is permitted because of preconceived notions that it is forbidden?
Does that outweigh the impropriety of a Rosh HaYeshiva talking about sex toys in public? I don’t know. Rabbi Boteach thought his way was fine. I suppose that Rabbi Linzer thinks that his way is fine too. But I wonder.
