Kim Richards has been in a committed relationship with Wynn Katz for six years, which sounds lovely and romantic. But, thanks to a shocking confession that Kim made on Marriage Boot Camp: Reality Stars, it turns out that there's something lacking in this particular relationship — and it's a pretty major thing.

In a preview of the episode released to Entertainment Tonight, Kim says bashfully: "[My boyfriend and I] haven't had sex yet, and I don't know if we can be intimate together." As her cast mates whisper amongst themselves (the general consensus: come again?), a coach asks The Real Housewives of Beverly Hills alum: "What is your fear with Wynn?"

Kim then took the plunge, asking Wynn: "Are you sexually attracted to me?" His heartbreaking response: "No." (Oof!) Later, in a confessional, Kim admits that her beau's answer made her "feel terrible." What's more, she said: "I just don't see a future with Wynn right now."

But when it was Katz's turn to share, he made it clear that the feelings of rejection run both ways. "You're not attracted to me," he told Kim. "When I kiss you — really kiss you and touch you — I don't feel any reaction back."

Well, it sure seems like the relationship counselors have their work cut out for them! And the couple clearly has some big decisions to make.
