Essential Sex Glossary Featuring 40 Common Sexual Terms

From sexual orientation to gender identity to different acts in the bedroom, here’s a glossary of basic sex terms: 1. __Agender__: A person who doesn’t identify with any gender identity, often preferring gender-neutral pronouns such as they. Agender is a gender identity, and it may or may not inform a person’s sexual orientation or sexual preferences. 2. __Anal sex__: Anal sex typically refers to anal intercourse, which is the insertion of a penis or strap-on into another person’s anus. The term “[anal sex](https://www.masterclass.com/articles/how-to-have-anal-sex)” can also be used to describe any sexual activity that involves anal play, such as rimming (licking the anus) or anal penetration by a sex toy or fingers. 3. __Asexual__: Asexuality is a sexual orientation in which a person experiences little to no sexual attraction. Asexual people may still experience romantic attraction and engage in romantic relationships. 4. __BDSM__: A blanket term for a wide variety of erotic practices and kinks built upon power dynamics between consenting sexual partners. “[BDSM](https://www.masterclass.com/articles/bdsm-explained)” is a combination of acronyms that stands for three similar but distinct communities that use power imbalance for sexual pleasure: bondage and discipline (B/D), domination and submission (D/s), and sadism and masochism (S/M). In general, BDSM involves one partner acting in the dominant role (or “dom”), while the other embodies the submissive role (or “sub”) as they both act out consensual fantasies. Both partners receive sexual pleasure and satisfaction from performing their role (whether [dominant](https://www.masterclass.com/articles/how-to-be-dominant) or [submissive](https://www.masterclass.com/articles/submissive-sex-tips)) during the sexual encounter. 5. __Bigender__: A person who identifies with both female and male genders. A bigender person may express two genders simultaneously or fluctuates between two genders. Bigender is a gender identity, and it may or may not inform a person’s sexual orientation or sexual preferences. 6. __Cisgender__: A person whose gender identity matches the gender assigned to them at birth, usually based on their biological sex. Cisgender is a gender identity, and it may or may not inform a person’s sexual orientation or sexual preferences. 7. __Clitoris__: The clitoral glans, commonly known as the [clitoris](https://www.masterclass.com/articles/learn-about-the-clitoris), is a small sexual organ at the top of the vulva that contains thousands of nerve endings. Clitoral stimulation is one of the most common and reliable ways for vulva owners to achieve orgasm. You can stimulate the clitoris with a vibrator or use your hand to rub, stroke, or apply heavy pressure for significant sexual response and powerful orgasms. 8. __Demisexual__: A sexual orientation in which a person doesn’t experience sexual attraction to a person until they’ve formed an emotional bond with them. 9. __Dry humping__: Also known as outercourse, frottage, or dry sex, [dry humping](https://www.masterclass.com/articles/dry-humping-explained) is a non-penetrative sexual activity in which a person grinds against another person or object to elicit pleasure. 10. __Erectile dysfunction__: A condition in which a penis-owner has a difficult time getting or maintaining an erection. Erectile dysfunction can result from a physical condition (like bad circulation or low blood pressure) or a psychological condition (like high amounts of stress or low self-confidence). 11. __Erogenous zones__: Erogenous zones are areas of the human body that are especially sensitive. During sexual foreplay, stimulating these areas can encourage relaxation, promote blood flow, build arousal, enhance sexual pleasure, and help you or your partner achieve orgasm. Common [erogenous zones](https://www.masterclass.com/articles/erogenous-zones-guide) include the armpits, lower abdomen, mouth, neck, breasts, buttocks, shoulders, lower back, and genitals. 12. __Fetish__: A nontraditional sexual interest that a person usually requires for arousal or sexual gratification. Though they are used interchangeably, a fetish is quite different than a kink, which is a nontraditional sexual interest that a person derives arousal or pleasure from but doesn’t necessarily require for each sexual activity or experience. 13. __Fingering__: Fingering is a sexual technique that involves manual stimulation of the clitoris, vagina, or g-spot during masturbation, foreplay, or penetrative sex. You can perform [fingering](https://www.masterclass.com/articles/how-to-finger-yourself) solo or with a partner of any gender identity or sexual orientation. For vulva owners, fingering the clitoris, a small sexual organ at the top of the vulva that contains thousands of nerve endings, is one of the main ways to achieve orgasm. Manually massaging the prostate gland (also known as the p-spot) can help penis owners reach a powerful prostate orgasm, which is typically more intense than penile orgasms. 14. __Foot fetish__: A foot fetish (also called foot partialism, podophilia, or foot fetishism) refers to a sexual interest in which a person requires a form of interaction with feet for sexual gratification. Foot fetishists may become sexually aroused by toes, toe or foot shapes, toenails, ankles, foot-related jewelry, accessories like socks and hosiery, or foot odor. A [foot fetish](https://www.masterclass.com/articles/foot-fetish-ideas) can come from various interactions, including imagining, looking at, touching, smelling, kissing, penetrating, or dressing men’s or women’s feet. 15. __Foreplay__: Foreplay is any sexual activity that comes before intercourse. The purpose of [foreplay](https://www.masterclass.com/articles/foreplay-guide) is typically to pave the way for sex, but good foreplay can be enjoyable enough to be the main event. Foreplay can involve making out, fingering, dry humping, and nipple stimulation. 16. __Genderfluid__: A person whose [gender identity](https://www.masterclass.com/articles/gender-identity-guide) is not fixed and changes over time.

A non-binary person may identify as both male and female, or neither.

Those born with a penis are usually designated male at birth. 35. __Polyamory__: The practice of engaging in multiple relationships (sexual or romantic) at one time; these relationships are called “polyamorous relationships.” Polyamory directly contrasts monogamy, in which a person is engaged romantically or sexually in one relationship at one time. 36. __Prostate orgasm__: The prostate is a gland in the male reproductive system that produces the prostatic fluid that mixes with sperm to form ejaculate (or semen). Located in front of the rectum, between the bladder and the penis, the prostate includes muscles that expel semen through the urethra during ejaculation. In addition to its role in the reproductive system, this gland can be stimulated for sexual pleasure and produce intense [prostate orgasms](https://www.masterclass.com/articles/prostate-orgasm-tips). In this capacity, the prostate has earned the nickname "the P-spot." 37. __Sexually transmitted infection (STI)__: An infection spread through sexual contact, whether by transmitting bodily fluids or genital skin-to-skin contact.
