I really really don’t want this to become reddit. Yes, some dudes are gross and/or homophobic. No, not all dudes. No offense OP but can we have higher quality questions please?
I would say this isn’t true and your partner is gross.
Holy crap no, OP. Normal people clean their everything. I’m sorry but your partner has issues on this.
Yes, some dudes are like that, unfortunately. Not the first time I’ve heard something like that. Some dudes also think that just the running water going there is enough to properly clean their ass.
The general consensus if you have such a partner is to run away. That is absolutely not okay under any circumstances. Don’t be a stinky asshole, clean your butt.
