I don't know. I never felt ashamed to what I masturbate, or what I use to do so. Maybe because my way of seeing it is that as long as I like it and it doesn't harm other people, there's nothing to be ashamed of.
(Of course, discretion and manners when talking about what one does in private is always recommended).

Guys quick question from someone new to this furry thing:
Is feeling shame and regret sometimes blacking out after climaxing to furry art natural ?
