This program from Physicians for Reproductive Health contains 20 modules. While originally designed for physicians it can be used by any youth-serving provider to learn about adolescent reproductive and sexual health care.
As HIV can be transmitted sexually, youth need to understand their sexual anatomy and different types of sexual activity. It is important that adolescent sex education lessons include basic male and female anatomical structures and physiology, where these structures are located, and their function related to sexual activity and reproduction.
To be inclusive of lesbian, gay, bisexual, transgender, and queer youth and to educate young people about the positive aspects of sexuality, lessons should include:
Beyond the four biological functions of reproduction, most people use their sex organs (penis, vagina) to express their attraction to or love for a sexual or romantic partner.
Female sexual and reproductive organs include (in alphabetical order):

In both females and males, the perianal region (area around the anus) and anus may also be used for sexual arousal.
Sex can be defined in many ways. While some people believe sex only includes vaginal sex (penis inserted in a vagina), sexual health experts know sex involves a spectrum of activities. Some people engage in no, some, or all types of sexual activity. Everyone is different and the way they express their sexuality is also different.
Types of sexual activity include (in alphabetical order):
While each activity is a way to express attraction to or love for a romantic or sexual partner, it comes with varying levels of risk for HIV, other STIs, and unintended pregnancy.
The sexual response cycle is the sequence of physical and emotional changes that occur as a person becomes sexually aroused in response to sexual activity. There are four phases in the cycle: excitement, plateau, orgasm, and resolution.
Pregnancy is caused by semen (ejaculate) or pre-ejaculate getting inside the vagina or vulva. Usually this occurs as a result of male orgasm achieved during vaginal sex. It may also happen if pre-ejaculate is released during penis-to-vulva contact without penetration. The most effective ways to prevent unwanted pregnancy are to: 1) choose not to be sexually active or 2) if sexually active, use a dual method (condom and another kind of birth control) every time.
