Speculation continues to grow that Tiger Woods is being treated for sexual addiction at a clinic in southern Mississippi.
This week, a 16-foot fence was erected around the Pine Grove Behavioral Health and Addiction Services clinic in Hattiesburg, Miss., to block out photographers.
Woods' rep has not returned request for comment, but if the 34-year-old athlete (who has not been spotted since his Nov. 27 car accident) is being treated there, he is likely undergoing intense therapy.
The program (which costs $37,000 for six weeks) is "emotionally exhausting," journalist Benoit Denizet-Lewis tells the new issue of Us Weekly (on newsstands now).
Denizet-Lewis — who was once treated for sex addiction and spent time at Pine Grove for his 2009 book, America Anonymous — tells Us that Woods, 34, "may be allowed his own room, but he'd still have to do group therapy."
Also required: A celibacy contract. Says Denizet-Lewis, "It says you won't have sex or masturbate while you're there."
Would his wife Elin, 30, be allowed to visit?
Yes, Denizet-Lewis tells Us; she would be encouraged to. British tabloids are already reporting that she has visited him.
