My boyfriend said he didn't want to have sex, so I'm going to force him to anyway.
Holy... that sounds a lot like rape? Why not just find someone that wants you instead?
My ex also said that, but then he spent the whole night doing it with me
I still think that you should wait until they consent to it. It is not okay to do things like that against your partners wishes.
I don't care!
You may not care, but you're pretty much raping your partner and that sounds very wrong, does it not? Do you want to make your partner scared of you and hate you?
