Thanks to this research, Dr. Meyer was able to make some sense of the mental disorders that were driving this request for unusual and radical treatment. Most of the cases fell into one of two quite different groups. One group consisted of conflicted and guilt-ridden homosexual men who saw a sex-change as a way to resolve their conflicts over homosexuality by allowing them to behave sexually as females with men. The other group, mostly older men, consisted of heterosexual (and some bisexual) males who found intense sexual arousal in cross-dressing as females. As they had grown older, they had become eager to add more verisimilitude to their costumes and either sought or had suggested to them a surgical transformation that would include breast implants, penile amputation, and pelvic reconstruction to resemble a woman.
