Human Sexual Responses

Sex is the act of copulation; termed coitus

Sexual responses cycle has 4 stages:

1. Excitement
- occurs with physical and psychologic stimulation leading to arterial dilation and venous constriction.
- In women; clitoris increases in size, vaginal lubrication, nipples become erect, increase BP, HR, and RR
- In men; penile erection, scrotal thickening, elevation of testes, and increased BP, HR, and RR

2. Plateau
- reached just before orgasm
- for women: formation of orgasmic platform, increased nipple engorgement
- in men: there's full distention of the penis

3. Orgasm
- the discharge of accumulated sexual tension; shortest stage
- an intense pleasure affecting the whole body, highly personal experience

4. Resolution
- the period during which the external and internal genital organs return to an unaroused state.

During second half of menstrual cycle, plateau stage is reached more quickly and achieved orgasm more readily. During pregnancy, increase interest in sex, and the increased breast engorgement may result to extreme breast sensitivity during coitus.
