There are soooo many myths about sex toys that I wish would just die, from the idea of them being "addictive," to the assumption that only awkward losers use them. (Both laughably false! I mean, hell, celebrities like Lady Gaga, Christina Aguilera and Chappell Roan have been open about using sex toys... Do you really think they're awkward losers?! Not to mention, even us awkward losers deserve pleasure!)
Another such myth, which I loathe, is that you should only use sex toys if you "need" them. Most recently I saw this raised in a Reddit thread about men using sex toys, and whether it is (or should be) more stigmatized than women using them. A woman was uncomfortable with her husband's new vibrating stroker, and tried to rationalize her reaction by saying that men don't "need" toys as much as women do, because men are more easily sexually satisfied than women – and that, for this reason, men using sex toys is somehow "weirder" than women using them.
It's certainly true that cis men's sexuality is often assumed to be simpler and more straightforward than cis women's sexuality in our culture, but the science doesn't totally back up that assumption. As I learned from Dr. Laurie Mintz's great book Becoming Cliterate, studies show that most cis women tend to reach orgasm without much trouble, so long as they're getting adequate, sustained clitoral stimulation – the same way that most cis men need adequate, sustained penile stimulation to reach orgasm. The clit and dick are effectively the same body part, after all; they just developed differently in utero. What’s good for the goose is good for the gander, and all that!
As I told the woman on Reddit who felt threatened by her husband's stroker, there's a reason they're called sex toys – it's because they exist for the purpose of fun and pleasure. There are occasional deviations from this – for instance, some sadomasochistic toys are more painful than pleasurable (although their diehard users may tell you otherwise), and some medical aids like vaginal dilators and penis pumps get lumped into the sex toys category even though their usage may not always be 'fun,' per se. But broadly speaking, sex toys are meant to be enjoyable tools for exploration and experimentation, like paintbrushes or musical instruments. Seen through that lens, it's obvious that you don't have to "need" a sex toy to be allowed to use one.
