Title. Basically I'm real tired of boyscouts MC.
Can you explain by what you describe as cheating?
There are are few stories/series where the MC looks to be cheating by outsiders, but has the full support/knowledge of their SO.
There are a number of stories where the MC is not cheating himself, but is causing many women to cheat:
Conqueror's Rise by Intrinsicvalud;
Older and Sexier by Caesar;
Owen Grows Up by Chemical Ollie;
No, Michael by Chemical Ollie;
Several stories by Just Plain Bob (usually they involve a revenge theme)
