There are some people who experimented with same sex relationships when they were younger but have since lived a straight lifestyle. They'll say that they find youthful people of the same sex attractive, but the thought of being with an older person or person of the same age doesn't do it for them.Maybe some people who have been with men but now only pursue women were more attracted to androgyny. So, when they were young and experimenting with another boy who hasn't developed body hair and other secondary sexual traits, they are attracted to them.
