One thing to keep in mind is that your average heterosexual male doesn't get tempted to be "curious" about other men in a sexual way; and your average heterosexual woman is even less likely to be "curious" about other women in a sexual way.
The "curiosity" develops when someone has a shaky gender identity, and there is an imbalance of masculinity/femininity. The little boy who has been treated like a girl by his mother, for example, and who has had minimal contact with a secure father or a father-substitute, is much more likely to develop a sexual interest in men. Just the other day, there was an article about a U.S. figure skater who has officially "come out" (even though nobody was the least bit surprised at his announcement). He said that as a six-year-old, he was watching Pretty Woman and developed a crush on Richard Gere. He said that he wanted to be Julia Roberts so badly, and that he wanted to kiss Richard Gere. It's pretty obvious that he was suffering from an overdeveloped feminine side and an underdeveloped masculine side.
Unfortunately, nowadays it seems that people jump to the erroneous conclusion, "I'm gay!" instead of the reasoned conclusion, "I am struggling with same-sex attractions. What is the reason for this, and what can I do about it?" Having same-sex attractions doesn't define who a person is--rather, it is something a person *has*. Similarly, if I have a broken leg or cancer, that's not who I *am*--it just means that a part of me isn't in full health.
I imagine that the guy in this article has probably had same-sex attractions for some time, but unfortunately he has now embraced them as his identity. That's a shame.
I wonder how many women have homosexual children after they kick “Dear old Crazy Dad” to the curb and marry their boyfriend.
