Like condoms, masks fail when you don’t wear them properly.
But condoms still work even when everyone else is stupid and don’t. Cloth masks, however, need everyone to wear them.

This is a terrible analogy. A single sperm escaping a condom can cause full failure of purpose. In contrast, any amount of decrease in the virus egress is good. There’s no binary. Illogical analogy.
In theory, a single sperm can cause a pregnancy. In practice, a man with a low sperm count can be unable to get a woman pregnant despite secreting millions of healthy sperm per ejaculation. So, there is a dose-response relationship even with conception.
In theory, a single virion could cause a case of covid, but in practice, it usually takes many more than that.
Again, though, the point is *less* virus is *always* better than more virus so whether or not single virion can cause illness or not is irrelevant. Decidedly not so for a single sperm getting through though. Hence, the analogy is terrible.
So I guess the opposite is true. If trying to get pregnant, more sperm is better, though in terms of prevention, a single one prevents full failure of purpose of the intervention whereas that's not true for masks (also a preventative measure).
