Question

Irene is listening to a romance novel while she is on her daily walk. although she is not walking especially fast, she finds that as she listens to one of the love scenes in the novel her respiration rate and heart rate increase. she is also experiencing vaginal moistness. based on the phases described by masters and johnson, irene is in which phase?

Answer 1

I believe the answer is: Excitement phase

During the excitement phase, our body would make various response to prepare us for upcoming sexual activities.
Each stimulation to genital area that initiated during this phase would gradually increase the excitement before it reach maximum point (which happens during orgasm)
