Looking for a Black-Mixed or Asian-Mixed donor

I am a 39 years old solo parent, living in Germany, and raising my 14-year-old. I have an academic background in Business Administration and currently work in the social sector as well as a coach. Education, diversity and personal development are important parts of my life.

I would love to have another child and am looking for a reliable, straightforward sperm donor. I would like a recent karyotype, STI screening and relevant genetic/hereditary disease testing. If these are not already available, I am happy to support/ cover the costs.

For personal reasons, I am preferably looking for a Black-Mixed or Asian-Mixed donor, as I would love for my future child to share some physical resemblance with my first child.

I am open to co-parenting, but it is not a requirement. We can openly discuss what kind of contact or involvement feels right for both of us.
