Baseball metaphors for sex
Among American adolescents, baseball metaphors for sex are often used as euphemisms for the degree of sexual intimacy achieved in sexual encounters or relationships. In the metaphor, first prevalent in the aftermath of World War II, sexual activities are described as if they are actions in a game of baseball.
Details and popularity 
Though details vary, a broadly accepted description of what each base represents is as follows:
- Strikeout – a failure to engage in any form of foreplay or sexual activity;
- First base – mouth-to-mouth kissing, especially French kissing;
- Second base – touching or kissing the breasts or other erogenous zones while clothed;
- Third base – manual or oral stimulation of the genitals;
- Fourth base (Home run) – "full" sexual intercourse.
The metaphors are found variously in popular American culture, with one well-known example in the Meat Loaf song "Paradise by the Dashboard Light", which describes a young couple "making out", with a voice-over commentary, by baseball announcer Phil Rizzuto, of a portion of a baseball game as a metaphor for the couple's activities.
Sex education 
Educators have found the baseball metaphor an effective instructional tool when providing sex education to middle school students. Levin and Bell, in their book A Chicken's Guide to Talking Turkey With Your Kids About Sex, make use of it to aid parents in the discussion of puberty with their children, dividing the topics into "first base" ("Changes from the neck up"), "second base" ("Changes from the neck to the waist"), "third base" ("Changes from the waist down"), and "home plate" ("The Big 'It'").
Recent changes 
This sequence of "running the bases" is often regarded as script, or pattern, for young people who are experimenting with sexual relationships. The script has changed slightly since the 1960s. Kohl and Francoeur note that with the growing emphasis in the 1990s on safe sex and efforts by feminist movements to expand sex beyond heterosexual penetrative intercourse, the "home run" has taken on the additional dimension of oral-genital sexual intercourse. Richters and Rissel conversely point out that "third base" has since become seen, by some people, to comprise oral sex as part of the accepted pattern of activities, as a pre-cursor to "full" (i.e. penetrative) sex.
