You don't cut the whole thing (O_O|||) only a little. If you cut it too deep well, then.. you can't feel...horny..anymore.. (Q^Q)
And It's actually good for health, why? because, you can avoid dangerous diseases like HIV/ AIDS. and for a boys, you can clean your...thing, better, you can avoid prostate cancer, kidney infection, and again, avoid HIV/AIDS (OvO) And again, for boys, you don't cut the whole thing, only cut the front cover skin of the peepee (OvOu)
