I used to think I preferred older, much older. I often had maternal transference. Ex-T turned out to be younger than me by a year. Then T is 2-3 years older and I have a great relationship with her. L is 3 years younger. I thought that would be too young, too inexperienced. I also thought I wouldn't develop maternal transference with someone who was my age or younger. Nope to all 3! L's been the best T I've ever had. I'm glad I gave her a chance. From now on I know better than to judge by age.
