It's unfair for women to masturbate using dildos and vibrators
I think it's unfair for women to masturbate using dildos and vibrators because many of the products sold are exaggerated in size and women get used to the feeling of being pleasured by very large objects, when in fact only a fraction of men are that well endowed naturally. This creates unrealistic expectations when it comes to actual sex. As a result the dating dynamics get incredibly skewed, and lead to statistics like 20% of men are having sex with 80% of women. Women's minds have just been warped to believe and accept that overly large phallic objects are the most satisfying, and this is unfair to the majority of men who do not biologically have such large penises.
