This thread was not about a debate over a society-wide problem. The OP, who had been dating a guy for nine months, found out her boyfriend had been having a ten-year sexual affair with his biological mother, a women he didn't meet until he was an adult. He described this woman as whorish and said she'd do anything and that he really liked it a lot. It was a big turn on for him.

He wanted to make it even better by having the OP participate in a threesome, with the girlfriend, at a minimum, watching as he received oral sex from this whorish older woman who would do anything.

She was almost convinced. Maybe it would help him. Good gracious great balls of fire! This is a serious problem for one woman, the OP.

I'm shocked at how easily her plight has been ignored as the conversation has rambled off into the issue of the value of incest taboos if procreation is not going to take place. That's not the issue facing the OP.

The boyfriend wants the OP to participate, at some level, maybe only voyeuristic, in a threesome with his mistress of ten years. The OP never said she was into threesomes or that threesomes were her thing. She was trying to figure out this surprising news from her BF.

If the whorish woman had not been his bio mother, just his mistress of ten years, a woman he's been cheating with throughout the relationship with the OP, it's likely the response would be nearly a single chorus of concerned posters shouting, "Dump him!" At least, that's the usual response when a woman has been dealt a blow like this from her partner.

I'm still shouting that. Girlfriend, dump him! I hope you're safe and well and taking care of yourself. Because you are the only person who matters in this entire conversation. I hope you'll come back and tell us how you're doing. Please take care, OP, my thoughts are with you. You and your happiness count!
