Feminism is a very selfish movement, for a given feminist, her motives likely have more to do with what serves her own interests than anything based on some ideologically consistent foundation. This means that it will manifest differently for different people.
For a girl who is hot and/or slutty, feminism will manifest as a way to minimize the consequences of exploiting her appearance and sexuality. For women who can’t or won’t do this, feminism can be a way of attacking sexuality and male desires.
To increase their power in society, women are going to want maximize the value of female sexuality. With the sexual revolution, women got lots of additional power because they could exploit their sexuality with impunity. Pornography potentially undermines this power though, because it gives men a relatively cheap and low effort method of gaining sexual satisfaction. Which makes it reasonable for some feminists to oppose it, sex workers are like scabs who push down the cost of sex.
“Body positivity” has always been self serving and hypocritical. You might hear plenty of feminists say that a woman who is a 2 deserves to date a man who is a 9, but in the next sentence they basically say that unattractive men are rapists for even daring to have or express sexual desires.
