Yesterday, a guy I've been seeing for about 4 months revealed something he was nervous about telling me: he was about to go donate sperm to a lesbian couple he's friends with. They had been planning this for about 6 months, prior to him meeting me. He didn't anticipate me reacting negatively to the situation and told me it was an unpopular opinion. I still have mixed thoughts and feelings, but I effectively broke up with him over it. Neither of us have kids and we're both still relatively young.
