To tease, or to "be a tease" in a sexual sense can refer to the use of posture, language or other means of flirting to cause another person to become sexually aroused. Such teasing may or may not be a prelude to intercourse, an ambiguity which can lead to uncomfortable situations.

Sexual teasing involves the possibility of sex, then the withdrawal of the perceived invitation. Teasing violates a standard piece of relationship advice—communicate clearly. But people often don't, especially in dating and the interpersonal dance that precedes sex.
