Do all men have the proverbial lisp and can therapy resolve that affliction?

Your question is unbelievable. I know lots of gay men and I do not see the majority of them having the lisp you are talking about. I would say that there are as many gays having a lisp as there are in the general population on a percentage rate and that percentage rate would be very, very low. You are uming that uality is a mental illness or deviant behavior and that is uming a lot. You don't know any more than many others what causes ity. I think your umption about the lisp that some exhibit is both insensitive and totally wrong. I am offended personally by your ideas and I am straight.
