TRANSGENDER OUTLOOK
by kiki whitlock*
Transgender is an "umbrella" term which describes different types of gender identities or gender expressions. There are male-to-female and female-to-male transgender persons. Some of the following categories are major groups within the transgender scope. Transgender refers to gender identity or gender role (Who am I? Do I feel feminine, masculine, etc.?), whereas gay/lesbian, bisexual, straight, and asexual refer to sexual orientation (i.e., same, both, opposite, or neither sex romantic attraction). Everyone has both a gender identity and a sexual orientation. A transgender person could be gay, lesbian, bisexual, straight, or asexual.
1. Major Types of Transgendered (TG) Persons or Roles
A. TRANSSEXUAL (TS): A transsexual person identifies and desires to be the other sex. Preoperative (before surgery) transsexual persons usually live "24/7" (full time) in the gender role in which they identify and most often take hormones of the gender in which they identify to change their secondary sex characteristics (i.e., smooth soft skin, more fat less muscle). Postoperative (after surgery) transsexual persons live "24/7" in the gender role of their choice, take hormones, and have gender confirmation surgery (GCS) to change the anatomical genitalia (penis or vagina) from one to the other.
B. TRANSGENDERIST: A person who lives "24/7" in the gender of her or his choice without wanting gender confirmation surgery. Some transgenderists consider themselves non-operative in status. Even some transgenderists consider themselves non-operative who might choose to take hormones.
C. CROSSDRESSER (TRANSVESTITE, CD or TV): A person who dresses in the attire of the other sex usually for sexual/erotic gratification or personal satisfaction.
D. DRAG: Generally, a gay, lesbian or bisexual identified person who crossdresses for functional purposes such as, social gatherings (parties), sex work, or personal satisfaction. Within recent years it has become a fad even for some straight persons to do drag.
E. FEMALE OR MALE IMPERSONATOR: A person with any sexual orientation or gender identity who performs a show or act by imitating someone usually through crossdressing. Many of these performers are career professionals who lip-sync, dance, or act a role by imitating a famous star.
F. GENDER BENDER: A person who sometimes expresses various types of gender roles or identities different from her or his anatomical sex.
2. Major Issues Involved in a Transgender Lifestyle
A. SOCIAL ACCEPTANCE and/or rejection from society; coping with potential harassment; issues of public accommodation (i.e., ladies vs. mens restroom issues); anonymity concerns.
B. PSYCHOLOGICAL - coming out; building self-esteem and confidence; giving and receiving emotional support with family and friends; one-to-one counseling and TG support groups with peers.
C. FINANCIAL/ECONOMICS - high medical expenses for hormone therapy, psychosocial evaluation, and genital reassignment surgery; survival and employment issues.
D. POLITICAL/LEGAL - transgender community empowerment and unity; employment, health care, and housing discrimination; change of name, ID and birth certificate.
