If you drink this holiday weekend, don't rape. And yes, if she says, "no" and you ignore that word because some girls/women mean "yes" when they say "no" your action will still be rape. Consent isn't about what some girls/women want it is about what a particular girl/woman actually wants and actually welcomes in that moment. Notice I didn't write that consent is about what you assume a particular girl/woman wants. There's a difference and understanding the difference might save you from what you would loudly and mournfully declare to be a false accusation.
If you don't drink this holiday weekend, still don't rape. No excuses.
I won't define genuine consent in great detail for you here. If you follow this blog you know the definition. But I will give you a hint, if you believe she might later, "suffer from morning after regret" as you like to call it and tell someone (possibly the police) at some point that what you did was a sex crime -- don't do it.
Grumble and swear about how feminists are ruining everything for men like you, but don't cross that line.
