Actually, I do use the terms "feminine-bodied" and "masculine-bodied," which is similar to this. There's nothing wrong with being sensitive to people, and if it confuses someone, they can certainly just ask (no question is a stupid question!). I do not think that it's people trying to get their word counts up either, as was mentioned, because most of the people who I've seen use the terms are just trying to be all-inclusive as opposed to "leaving some individuals out."
There's nothing wrong either way, with saying "this works very good for the g-spot" or with saying, "this works well for female-bodied individuals." On most reviews I've read, they've clarified both - that the product is good clitorally AND for feminine-bodied individuals. Now, as for anally, I've never seen a person say that something's only made for "a man" for anal. That's a bit unnecessary, considering the fact that most people do have a functioning anal canal. But to say that it's better for the p-spot? Sure, why not?
I do not understand, though, what the problem is either way. I have not seen a review where they've only said, "This is good for women," "This is good for men," "This is good for female-bodied people," "This is good for male-bodied people," without describing the toy's function or what body part(s) it works well on.
As I side note, I hate the terms female- and male- bodied. Which is why I use feminine/masculine, because a transgendered man's body is male, no matter what it appears to be, same with a transgendered woman. But then again, I use terms that I've never seen people use - like my "trans-" use. I use "trans-" because a person may be a number of different forms, like transgendered, transsexual, a transvestite. I use "trans-," because, to me, it's more inclusive than the now-umbrella term "transgendered."
Alright, to answer the original post and my idea on it, if I was not clear: I think that it's fine that these words be used. I also think that it's fine if they're not - I'm not personally offended by people who do not use them. I do not feel that they add confusion, other than to those who do not understand them, who, by all means, can ask if they are confused. I also do not feel that they NEED to be used though. Use of a word is not needed, so I do not believe that that term is good. Should they be used? Perhaps, depending on the situation. Will they always be used? No, they won't.
Is it really such a bad thing, though, to use them? Because I am not understanding how it's so bad, if the person also clarifies the anatomy that the product works well on. If it's confusing to someone, they should feel just fine asking the person who used the term what it means.
