If interested check out the non-fiction work of Sperm Wars.

Basically it means that somewhere in evolutionary biology men became aware that women were having sex with other men. Also women seem to be able to spontaneously abort a pregnancy if they feel they have been caught 'cheating'.

So biology, it seems, has one idea that is very different to the commonly expressed morals.
