I had strong paternal transference for my former marriage counselor, and he was only 12 years older than me. So I don’t think it’s necessarily about age. Though he also talked about his kids (teens at the time) a lot, which I think contributed to the transference. Current T is 7 years older with an 11-year-old don, but he doesn’t talk about him much at all. I don’t feel that I have paternal transference for him, he feels more like a contemporary.
