Premature ejaculation is classified under the orgasm phase of sexual response cycles. It occurs when ejaculation happens sooner during sexual intercourse than a person or their partner wishes, which can lead to distress and interpersonal difficulties. Understanding the phases:
- Excitement phase: Initial arousal and physiological responses begin.
- Plateau phase: A period of consistent intensity before orgasm.
- Orgasm phase: Peak of sexual pleasure, leading to ejaculation in males.
- Refractory phase: Period after orgasm where further arousal isn’t possible immediately.
Premature ejaculation is specifically related to the challenges in controlling ejaculation, thus categorizing it within the orgasm phase.
