had spoken to him about his views on any of this...seems reasonable to me...but you said you didn't and I haven't mentioned him since, nor will I again...while we're at it...please don't bring up my grandkids or any other members of my family in any way that touches on this topic of yours...I certainly didn't invite you to do that...
As for "perversion"...there is a very wide spectrum of behaviors that elicit that view...as a link I posted shows, there are scores of 'popular' acts that would qualify...from "Bondage", to "SadoMasochism"...to "Role Playing"...take your pick...but, so long as the behavior doesn't cause damage to the person or others, it's none of your concern how those persons get aroused.
For my part, I accept that millions of people fit your description of "perversion"...my only concern is that they don't let it hurt themselves or others...your posts represent the only times the issue comes to my mind...it's all on you as to whether you keep pushing this, or move on.
