Someone please tell cis men that talking about their ejaculate is probably not a good way to entice someone into wanting to have sex with them, especially when the person they're trying to have sex with has already told them a dozen times that they find it appalling.
Or, to put it shortly: Someone tell cis men to fucking listen to their partners, full stop. About everything. And not just about sex but also definitely about sex, including initiating sex.
If your partner doesn't like something, doing more of that thing ISN'T GOING TO HELP YOU. And the only person you have to blame when you don't get what you want is yourself, even if you're more likely to blame your partner for “not being nice.”
