Chaz Bono has told Rolling Stone that he's saving to have more surgery performed.

The 42-year-old Bono's gender reassignment surgery was chronicled in the Emmy-nominated documentary Becoming Chaz. A follow up film, Being Chaz, focused on his now-ended 6-year relationship with Jennifer Elia and the controversy that surrounded his appearance on ABC's Dancing with the Stars.

Bono is surprisingly candid about such a personal decision in the interview.

“I could get a phalloplasty, which builds the phallus from a donor site on your body,” Bono said, “but I'm leaning more toward a metoidioplasty. It's a procedure that uses what you already have down there which has grown larger from the testosterone. You end up with a smaller phallus than with the phalloplasty, but it's fully functional, it gets erect, and the sensation is all there.”

Bono added that he wasn't sure about size: “I've never seen one erect. So it's really hard to say. But, you know, soft, probably about three inches and it grows considerably. I don't know what the average size difference is, but when I'm having sex I probably get three or four times larger.”

The surgery, Bono added, would cost between $25,000 and $45,000.
