My wife and I want a child, but I'm infertile and can only have sex with a sperm donor. (Yui Hatano MRSS-135)

I have male infertility, so I decided to use a sperm bank. I want to preserve my good genes, so I consulted Mr. Hirasawa, a top-tier donor—handsome, IQ 141, and incredibly athletic. However, Mr. Hirasawa said he only provides sperm through the safe period method, "sperm donation via actual intercourse." I don't think that's a problem, because I said I want to have viable intercourse without love, but as a husband's servant, it's a disgrace for my wife to be embraced by a man I don't know...!
