In general, the way older women flirt does not fundamentally differ from how younger women do it. However, there are some differences due to a woman’s age and experience.
Most mature women are more open and straightforward in communication with men than younger women. For example, a woman in her 60s will look at you and hold your gaze, smiling at you friendly. She will initiate the conversation and listen to you attentively. Or she will give you compliments and touch you occasionally while talking to you.
Again, this openness in flirting comes from a woman’s experience and confidence. Older women know what they want from a relationship, so they usually waste time sending blurred signs.
