I am currently doing this. Skipped the first roll as I am afraid putting it in my vagina will give some health effect. Because vagina is generally more prone to infection compared to ass. I hope you dont mind
Anyways I put the ginger in my ass, wore the tight panties (and nothing else). For me the dare lasts 10 minutes
It burns very intense since the first 30 seconds. and I think it is really something that can be used as punishments.
But to me it is still bearable
