"Russell, who was married four times and had numerous affairs, believed that both men and women should be allowed to have pre-marital sex."

I want to buy his book and distribute free copies.

I do think a more mature approach to long-term relationships is due in western society, but I also think this is highly individual. I'm not sure I could ever stray, even with the understanding that extracurricular activity is permissible, but I wouldn't stand in the way of my partner if she wanted something on the side. I don't own her, after all, and she can maker her own decisions. Russell is opposed to casual sex and, for myself, so am I. But I think a lot of people successfully navigate casual sex, effectively separating deep and loving relationships from exciting sexual flings. If my partner felt the need to stray, I hope she'd be honest with me about it and take precautions to maintain our relationship as the primary. That might mean being careful to not develop a deeper connection with other men or women, keeping it somewhat casual. I understand what Russell means about not decoupling sex from love, but I think maybe there are ways to maintain a loving relationship with one person while satisfying other needs and desires with others.
