Again:
Misogyny (/mɪˈsɒdʒɪni/) is the hatred or dislike of women or girls. Misogyny can be manifested in numerous ways, including sexual discrimination, belittling of women, violence against women, and sexual objectification of women.
Of which this thread is overflowing with.
My last post here: OP has all the right to NOT want to participate in threesomes. If that is what she wants, which she never expressed, or OP failed to mention to us, then, please, break up, and you are not a bad person for doing so, as if this is the case, you both are just sexually incompatible. But OP himself said he can't even look at her the same way since that, how is that not judgement? She did it before, OP. And this is not to mention the double standards in this thread as well.
That being said: congratz on the sex, op's girlfriend. God speed on your sexual adventures. Be safe, and enjoy your life.
