>>7424801use your asshole on your foreskin/glans or your scrotum/perineum
But ther are better things then capsaicin, like ginger, cassia and anise (use a enema syringe for your ass)
Also you can use menthol for the opposite effect
If youare hardcore you can use a dilator apply it to your urethra, but don't use chilli pepper for this, use pepper spray mixed with water instead
it's a nice feeling to have a warming transrectal application with some menthol cooling on the perineum
