How indispensible
E2 is in matters like this. Hehe.
Anyway, another substance that is not advisable to use in masturbation is hot sauce. I heard a radio show similar to MTV's Loveline at one point, and some guy called in and said he's tried the act with this substance - as well as shampoo.
I'm no expert in lubricants of this sort, but I'll just say for the record that I would at least not try it with hot sauce, or anything else that would make my eyes burn if I got it in them.
So this guy says that in the course of pleasuring himself, he got some hot sauce in the "hole" (better known as the urethra) and seemingly, it stung pretty bad.
I all I can say is, ouch. So while you're adding Icy-Hot and Ben Gay to your list of things NOT to whack off with, put hot sauce on there too. You can thank me later.
