If semen started off incredibly unsafe to have in other people's bodies, males with the least harmful semen would be more reproductively successful since the females they had sex with would be more likely to survive. People don't generally exchange blood, so there's not any strong reason why ingesting other people's blood would need to be safe.
Semen is less associated with sickness and injuries than blood is. If someone's injured, there will probably be blood around. If someone's sick, there might be blood around. We then end up associating blood with unsanitary things.
Blood's a really effective vector for disease. So is fluid exchange during sex, though, and I'm not sure to what extent blood is actually worse. I know sex gets much riskier for the person with open wounds if someone has open wounds.
Semen doesn't produce such vibrant stains compared to blood?
Also, like, menstrual fluid contains not only blood but also other things, like shredded chunks of discarded uterine lining, which are pretty disgusting. I've desensitized myself to this somewhat because I used to have really heavy periods, but if anyone expected me to be up for ingesting pieces of dead, decaying human organs, I would consider that person to be completely unreasonable.
