Strange question.
I HAVE "platonic relationships" with married middle aged women right now. I.e... I work with them... one of them does the payroll... several of them are architects I work with.
They all seem to appreciate my work, and ask me where I'm going when I take holidays. That's by definition a platonic relationship.
There is absolutely no question in my mind about whether there could every be anything sexual there, and I like that tbh, it makes life easier.
