Thanks for the caveat of “in my own personal experience.” I’m sorry this is your experience as it sounds like a very painful and limiting one. To your last sentence, that doesn’t sound like a real friendship at all, it sounds more like you’re being used as someone’s pet, or pseudo relationship, or fallback plan, and therein lies the real problem. Anyone can choose to avoid people who they find personally “tempting” if they worry about being unfaithful. But if men (or women) are constantly going through life worried about being unfaithful, they have a deeper problem that begs some analysis. It’s like when you have been traumatized, everyone suddenly seems like a threat until you work through said trauma. In this case, they are probably over-sexualizing others or unhappy with their own romantic/sex lives, therefore they have a lens of sexualizing or romanticizing every eligible candidate they see. That would be a no-fun existence and I hope people who feel that way can find help. You’re right, it is impossible for some men and women to be friends if they can’t see each other as people and not tools or toys to use for their own ends.
