It's a possibility, but of course depends on those involved. Some people like to explore bisexuality specifically, so they only want to venture out with same-sex partners as they've already found their opposite-sex partners. But others are primarily heterosexual, and my not find the satisfaction they're looking for in same-sex relationships.
If a woman is in a OPP marriage, and she's dating other men but not sleeping with them, most of those men will eventually lose interest for milkier cows. That may eventually cause her to become frustrated with the arrangement.
All of this can be compounded if the OPP is a double-standard, where the wife is expected to bring home other women for threesomes. Naturally that can upset the balance of things.
