Yes potentially there was "mutual rape" or whatever you want to call it.
The point of the poster is that a) rape charges against men are often prosecuted, b) going to parties to find "easy women" who are to drink to legally consent, even if you are also at the same level of drunkeness, isn't a great idea.
If the poster is sexist, it's mostly just trying to market to its audience and the legal realities.
This is a poster trying to get 18 year olds to moderate and consider their behavior, not be a treatise on law or gender studies.
See: MRAs failing to understand how this kind of "reverse sexism" is really just the same patriarchy that feminists describe, and that basically every "gotcha" example is really just an example of patriarchy hurting men... In exactly the way feminists have been describing for decades.
I'm kinda curious. What if it was Jake with Jim, and Josie with Jill? Do both Jake and Jim get prosecuted for mutual rape, and neither Josie nor Jill do, or is it the reverse? Do neither of the men get prosecuted because men always want sex? Do neither of the women get prosecuted because women can't commit rape? This is all so confusing.
As an aside, I[M] had a woman try to get me to go home with her at a club a few years back. She had obviously been drinking. I declined, both because she had been drinking, and also because I'm not really into hook-ups. (A date to get to know her? Sure. A one night stand? No.) But I have to wonder - maybe she really, really wanted to get laid, but was nervous about hitting on men and possibly being rejected, and used alcohol as a way of being less rejection-sensitive? Shit's weird.
Under patriarchy, men are the only ones seen as having agency so they are assumed to always be the aggressor. The assumption is true, even when the reality is not. At the same time, men are socialized to ignore boundaries meaning that most of the time they will be the aggressor, reinforcing the assumption and justifying the application of laws that align with that assumption.
Men will always be the abusers and never the abused. Men will never be seen as the care givers, even when they are the actual care givers. Men will always be the rapist, never the victim. And, because society tells men these things, we often enact them against our own interests.
The fact that this logic doesn't make sense is something feminists have been calling out for a long time as part of the larger system of patriarchy. While patriarchy usually gives more power to men, it doesn't always. But even when it does seem to benefit men, it still harms men... Just like how every other system of oppression harms everyone involved, not just the oppressed.
Some people say so. The real issues are 1, people who don't care if the other person consents (actual rape) and 2, people, mainly young women, who regret it the next day and think they can revoke consent after the fact (not rape).. and the biggest issue with those is figuring out which one actually happened since both are unfortunately a thing. If they don't do enough for column 1 that's bad, but when they go too far for column 2 that's also bad.. it's a mess.
"Wait WHAT DID SHE??? I did not consent! Just because the consumption of alcohol does erect my penis does NOT mean it is consensual! She used me for my semen!
