works if you have nothing else, kinda burns though lol not to mention it will render a condom useless by eroding tiny holes in it. (I draw that conclusion on the basis that using lotion as lube does that, so I assume that conditioner would do the same.)
So yeah if you're trying to have safe sex, don't use conditioner.
when i worked in an ER, i saw my share of people who used hair conditioner for anal sex.
belive me; you just don't want to know, what they went through, due to putting hair conditioner into their assholes!
