It honestly depends how truthful you want to be. The first is men are allowed to talk about issues with other men without being judged for it. So it could be “I’m worried I don’t make enough money for my family” they wouldn’t want their family or family’s friends around then. Could be “I’m having this sex issue”. Could be “this one night stand sexually abused me and if I tell anyone she told me she will go public that I raped her when I was the victim!”. Without men only spaces those conversations can’t happen because you can’t say “oh I’m going to,” actually where? haha I can’t even think of an example where a man can go to talk about sexual violence, thats how bad it is. But I meant “oh I’m going to go to this sexual violence clinic for men and it will be in secret so you don’t know I’m going” it needs to be a casual place that allows for other conversations.
Now this is the controversial part that will divide people. I think most men simply just enjoy men only spaces some of the time. They feel less judged and they feel it’s more friendly. I honestly think men only spaces are important to mens health because they can enjoy themselves and act “normal” they can act in a way that feels natural to them rather than acting the way women find socially acceptable.
