A good idea would be to get a mentor. They can help you step-by-step with your review at a more personal level. Also, this
thread that I made a while back may be of use to you. Really, you only HAVE to use the lube like YOU want to use it. I mean, YOU bought it so that's your right. But it's nice to say if you think it might be good for other things. In my first lube review here
, I had sections detailing if it would be good vaginal sex, anal sex, oral sex, toy sex, and masturbation. I'd say that pretty much covers all grounds.
EDIT: It looks like you already have a mentor so scratch that. Lol. You have a good mentor. beck's an awesome reviewer.
