I have a personal disgust towards virgin shaming/slut shaming, it reinforces the ideology of how men are to be the conquers of the women and the women are to be obedient and self preserving (this is coming from a male feminist btw).
It goes hand in hand with our gendered linguistic system, how insults that people normally use target one aspect of men and one aspect of females. Men's pride and manhood are targeted by insults, being called "******," "gay" (making a connection between homosexuality and an undesirable male), "pussy," "*****" (basically calling a man a women), and other such words, all of which targets one's manhood and willingness to be what society defines as being a "man." same thing with women, except when insulted it's their self preservation and sexuality that's targeted. Being called "whore," "*****" (a female dog in heat), "slut," and the filthiest word, "****," which is basically all of those other words combined into one.
And FYI, I'm a liberal feminist. I'm for the equal rights, equal treatment, and generally equal standards for both men and women. I recognize the kind of oppressiveness exhibited against women, but that has diminished vastly over the past couple of decades. I do not demonize men.
