I want my T to be older than me, but not too old. PrevT was only 3 years older than me. It worked out fine, but I did compare myself to her a lot and I wasn jealous on her. Current T is 13 years older than me. So far it's going alright. I don't compare myself to her and that feels better for me. I feel a little bit less afraid to me judge by her, it's easier to tell her certain things.
