Well, that will require the same compliance on both sides... the girl is a vector, too.
This is incredibly irresponsible. These people (and anyone they influence in this regard) will be the cause of many needless deaths.
If I feel like I’m not ready to take a relationship a step further, but my (future) girlfriend is, I’ll let her know that I’m not ready, and I’d hope she would respect my decision.
If she can’t, then I still would be saving myself.
