Los Angeles, Feb 6 (IANS): Actor Matthew McConaughey was so worried about the possibility of contracting HIV when he was a teenager that he spoke to three doctors about preventive measures.

The 44-year-old, who plays AIDS sufferer Ron Woodroof in “Dallas Buyers Club”, admits he was so concerned about the rise in the sexually-transmitted infection while he was growing up in the 1980s that he sought advice from health professionals, reports contactmusic.com.

''I remember in 1988 I was a senior in college and as a heterosexual young man becoming sexually active I remembered getting worried and what I clearly remember is talking to three different doctors and saying, 'Give me some science on this. 'I'm a heterosexual man and I'm having . . . I'm not being too loose but give me some percentages, give me something . . . ' and they had three completely different answers about what the risks were so I came away from that being more scared.

''I remember thinking, well, I'm gonna go with the guy who said be the most cautious. But nobody knew at the time, the doctors didn't know,” he said.
