Seeking a Portuguese sperm donor

Hi there, we are a married lesbian couple from Sussex, UK seeking a Portuguese sperm donor. I am of English/Irish decent and my wife is Portuguese, from Madeira. We are only open to considering artificial insemination. We would like to start the process in 2022 but it would be great to find our donor in advance of that and spend some time getting to know each other. Any questions, please ask! Thanks, Amy
