OUR SEXUAL AND REPRODUCTIVE ANATOMY
TEACHING TIPS
A. Potential problems
Some students who enroll in human sexuality will begin the course thinking that they know a great deal about the subject matter. However, never assume that they know anything. I have found, for example, that a few students are unable to identify the anus in an unlabeled drawing similar to Figure 2-2. Also, do not assume that all the students have some familiarity with the correct anatomical terms. Most of the students begin the course using a slang vocabulary and some may have never used even the most common terms (e.g., penis, testicles, vagina).
Perhaps the biggest problem at this stage of the course will be the students' anxiety level. Most of them have never even talked to their parents about sex and are not used to anyone talking so openly about the subject, much less showing slides or drawings of male and female genitalia. Anxiety often translates into childish giggling and talking. It is a good idea to spend some time "breaking the ice" before you lecture about anatomy. A good way to do this is to address the students' use of slang terminology (see B and C).
B. Media resources
1. "Breaking the Language Barrier, Sexual Slang," distributed by Focus International, Inc., is an excellent slide series designed to relieve anxiety at the beginning of a human sexuality course. The slides are ordered in pairs; the first of each pair shows the proper name for part of the sexual anatomy or for a sexual behavior. The students are instructed to say (out loud) as many slang terms as they know for each. The second slide then shows numerous slang terms. I have used this with great success. It “breaks the ice” and helps relieve initial anxieties and embarrassment. However, I have encountered problems when there is a large enrollment—students not enrolled (almost always men) may attend class that day just to try to be gross. I find that this exercise works best after the first two or three lectures, just before the anatomy lectures.
2. See if your biology (or anatomy) department has models of pelvic anatomy that you can use.
3. “Your Pelvic and Breast Examination” (12 minutes), distributed by Perennial Education, shows in good detail these two very important examinations for women. Great for relieving anxiety.
“Living with Prostate Cancer” (28 minutes), distributed by Films for the Humanities & Sciences, is another film taken from a Phil Donahue program. It is a relatively short, excellent film for men.
“Fire Eyes: Female Circumcision” (60 minutes), distributed by Filmmakers Library, examines the medical and socioeconomic aspects of this custom that is common in some parts of the world. A long film, but very good if you are emphasizing cross-cultural aspects of sexuality.
C. Classroom activities/Discussion
1. Use the slide series (B-1 above) to relieve anxieties. Alternatively, write the proper names of the sexual anatomy and several sexual behaviors on the blackboard and have the students say (out loud) as many slang terms as they know for each. Discuss whether the slang terms have positive or negative connotations and why we often use terms for sexual body parts and functions in a negative manner.
2. Have the students label drawings (unlabeled) of the sexual anatomy.
3. Discuss possible double standards regarding the male and female genitals (e.g., most men are not ashamed of their genitals, but many women are).
4. Have the students discuss the role of breast size in (a) a woman's self-concept, and (b) men’s views of femininity and sexuality.
D. Outside activities
1. Have the students examine their own genitals at home in privacy and identify as many parts as possible (women will need a hand mirror for this). Anticipate that some students will have difficulty with this and discuss the importance of a positive self-concept as well as the idea that no one should be ashamed of their own body.
2. Tell the students to give themselves a breast or testicular self-examination and to write a one-page paper describing the results (to ensure that they have done it). Give the addresses and phone numbers of local sources that conduct pelvic and prostate exams. Give extra credit to anyone who has such an exam done during the course
