And that is an excellent example of what the author is trying to say. Our culture has rules for relationships between men and women. Few tolerate a 50 yr. old man hitting on a 16 yr. old girl. We send them to prison. When Gerry Studds took a 17 yr. old boy to Europe for a sexual escapade, he was rewarded with reelection multiple times.
In England there was a referendum to lower the age of consent for gay boys to 14, stating that they we more sexualized then straight young men. I don't think it past. But in gay circles, most of the sexual moors that we take for granted do not apply.
Straight healthy sex culminates after a friendship evolves to love and is the celebration of that relationship. Ultimately, it brings about a family.
Gay sex is about sexual gratification.
Not always - in some states, with parental consent, they get married. Is it the age difference, or the outside-of-marriage, promiscuous sex that's the problem? Perhaps our society needs to rethink its objections to marriage of 16-19 year olds.
