@winsor I think asking for things like that is tricky and would make things probably very difficult to find the right person. I think you have to be practical about the most important aspects of a donor, things like medical history including mental health, age, pregnancy and ttc history etc and also whether their mindset is inline with yours in terms of whether you want them to have any involvement in the child's life. Then theres the practical stuff like their location etc. Unless there was a medical reason why the person had to be the same then I would say its not important. But I don't know anything about that stuff.
Just my opinion tho..
