GILLIAN Anderson had a relationship with a woman while she was in high school.
The former X-Files star has experimented with her sexuality in the past but says she was too attracted to men for her lesbian romances to go the distance.
She told Out magazine: "I was in a relationship with a girl for a long time when I was in high school.
"If I had thought I was 100 per cent gay, would it have been a different experience for me?
"Would it have been a bigger deal if shame had been attached to it and all those things that become huge life-altering issues for youngsters in that situation?
"It's possible that my attitude around it came, on some level, from knowing that I still liked boys."
The 43-year-old actress started to experiment with her sexuality after her family moved from London to a small town in Michigan.
Gillian - who has two sons, Oscar, five, and three-year-old Felix, with partner Mark Griffiths as well as 17-year-old daughter Piper from her marriage to Clyde Klotz - said: "Going from London to a small Republican town like Grand Rapids was quite a shock.
I thought it would be a place of sunshine and happiness and candy bars.
"Based on how I chose to look, dress, behave, you know -the relationships I was in at the time were freaking people out."
