I have been seeing someone I met through work, everything is going great and I really like him. However he has just dropped a bombshell. He told me that he is a sperm donor and has been donating for 5 years which has floored me. I don’t have an issue with donations to help people get their dream of having a baby, I think it’s a lovely thing to do for someone, but I feel strange about the fact he has a lot of biological children out there. He claims anything from 30-50 babies have been born so far. If we ever had our own children they would have half siblings dotted around the country, possibly meeting accidentally, and it makes me feel uncomfortable. Would you overlook this if you really liked someone or would it be a dealbreaker?
