Tôi muốn chơi tay ba nhưng người phối ngẫu của tôi không muốn và tôi không biết lý do tại sao

I would like to have a threesome but my spouse doesn't want to and I don't know why, I told him that I would behave, that I would just let him put it in me without a condom and his friends that they do put on a condom, but he doesn't want to
