A growing number of young men today say they are “mostly straight” and yet feel a slight but enduring desire for men. Ritch Savin-Williams explores the stories of 40 mostly straight young men to help us understand the biological, psychological, and cultural forces that are loosening the sexual bind many boys and young men experience.

Most of us assume that sexuality is fixed: either you’re straight, gay, or bisexual. Yet an increasing number of young men today say that those categories are too rigid. They are, they insist, “mostly straight.” They’re straight, but they feel a slight but enduring romantic or sexual desire for men. To the uninitiated, this may not make sense. How can a man be “mostly” straight? Ritch Savin-Williams introduces us to this new world by bringing us the stories of young men who consider themselves to be mostly straight or sexually fluid. By hearing about their lives, we discover a radically new way of understanding sexual and romantic development that upends what we thought we knew about men.

Today there are more mostly straight young men than there are gay and bisexual young men combined. Based on cutting-edge research, Savin-Williams explores the personal stories of forty young men to help us understand the biological and psychological factors that led them to become mostly straight and the cultural forces that are loosening the sexual bind that many boys and young men experience. These young men tell us how their lives have been influenced by their “drop of gayness,” from their earliest sexual memories and crushes to their sexual behavior as teenagers and their relationships as young adults. Mostly Straight shows us how these young men are forging a new personal identity that confounds both traditional ideas and conventional scientific opinion.
