yo a couple years ago I was dating a girl who tried to tell me about this shit one night! I really tried to listen without becoming terrified that I might be dating a lunatic but the more she talked about what she was into the weirder it got until the end when I was just nodding silently realizing that I simply was going to be unwilling and unable to accommodate this particular kink. Without sounding like too big of an asshole it kinda seems like ppl who are into this had really bad childhoods.
