Say what you will about Charlie Sheen’s unconventional home life with his two girlfriends, but his “Goddesses,” as he calls them, wouldn’t have it any other way.

“I’ve always felt that a man should be able to be with as many women as he likes,” says Rachel Oberlin, 24, one of Sheen’s two live-in girlfriends. “I’ve never had the opportunity to share that with any man before because, honestly, I don’t think I’ve ever been with a man who was even deserving of that.”

“Charlie,” she continues, “is a great man and he can provide the lifestyle to accommodate a relationship such as what the three of us have. He has totally taken me aback by what a wonderful person he is, how open and honest he is.”

But do Oberlin and Sheen’s other girlfriend, Natalie Kenly, 24, ever find themselves vying for the star’s affection?

Nope, insists Oberlin. “[Henly] is totally chill and I’m totally chill and we’re two completely different people,” she says. “We connect with Charlie in different ways, so there’s nothing really there to compete for. We’re all pieces of a puzzle that fit together.”

Although Sheen, 45, is entangled in a custody battle with his estranged wife Brooke Mueller over their nearly 2-year-old twin boys, Max and Bob, the Goddesses have had no qualms about helping Sheen take care of the kids.

“I adore them,” says Oberlin, a former porn star whose screen name was Bree Olsen. “I’m just a really loving, passionate, compassionate person. My heart just goes out to children. I was playing with the boys [on Monday], and I was holding little Bob and I just didn’t want to let him go. It was so cute.”

As for Sheen, he sees little wrong with The Goddesses playing a role in the lives of the twins. “If I feel totally comfortable and there’s nothing but love and support and compassion and all things good, then I see nothing wrong,” says Sheen of his unique domestic arrangement. “Who has a better vote at the end of the day than their father?”
