Being unfaithful is nae big deal imo.
Females are slightly nuts and can change over a period of time, if their attitude towards the likes of cleaning, sex and blowjobs becomes somewhat lackadaisical.
Then quite rightly, they should be nervously looking over their shoulder. And if it does happen then they would need to take a good look in the mirror as to why it happened.
And the male can simply hold his head up high.
