Document Summary

Excitement phase, orgasm phase, resolution phasemasters and johnson"s model. Nts act in this process, especially no (viagra works on no system) Nts epi and norepi are involved in making the erection go away. In women the capillaries in vaginal walls dilate, fluid seeps through semipermeable membrane of vaginal walls for lubrication. Women get the orgasmic platform as more aroused (tightening of bulbospongiosus muscle around vaginal entrance making it tighter), clitoris erects (no nt), nipples erect, sex flush (men and women) In men the scrotum thickens, the sac tenses so the scrotum is pulled closer to the body, spermatic cords shorten so testes are closer to body, and tension causes orgasm. Stage one is ejaculatory inevitability when vas, seminal vesicles, prostate contract to force cum into a bulb at the base of the urethra. Second stage the urethral bulb, base penis muscles, and urethra contact to force semen out of the urethra.
