typical of most people most of the time when they have orgasm o Dashed line indicates some people have another orgasm Women are more apt to have a second orgasm than other people Resolution body returns to unaroused state Refractory period men enter this after resolution period of time where it will be impossible difficult to get an erection amp impossible for him to have an orgasm Some women have a refractory period Takes the body longer to go back to unaroused state if you don t have an orgasm Changes During the Sexual Response Cycle in Males lLl crcclZd I uptake HLECI JlYJh Excitement

accommodating outer third 2 to 3 inches innermost part of the vagina expands tenting amp length of vagina increases Orgasm uterus amp orgasmic platform contracts What about NeuroChemicals There are some studies that show each of the following is involved with sexual arousal and or orgasm o Dopamine o Norepinephrine o Oxytocin o Prolactin o Vasopressin But exactly which amp when there is much inconsistency in the research results Criticisms of Masters and Johnson s Model Ignored psychosocial phenomenon 0 Most of their participants weren t in relationships Participants had to be orgasmic Mechanistic o If you do not follow 4 phases you are not sexual Responses to Criticisms Decided to study physiology only 0 They were a physician and a biologist gynecologist so that s what they knew 0 Techniques for studying psychosocial emotional responses were not well developed at the time of their studies 0 Later work demonstrated they were aware of the importance of emotional and interpersonal factors Orgasmic people only 0 They wanted to study sexual response so they needed people who responded well sexually 0 They believed they were studying a basic process that would work the same in all people Did not allow for variation from their mechanistic 4 phases 0 Yes they did see slide 4 0 Note slide 4gt continuous process 4 phases for convenience only Question on test describe general nature of Masters amp Iohnson model 0 Continuous process that for convenience they divided into 4 phases PsychoPhysiological Model Triphasic Model Helen Singer Kaplan s triphasic model of sexual response 0

excitement amp plateau phase focusing on pleasurable feelings Surrender corresponds to orgasm totally let go Re ection re ect back on what happened Bancroft s Dual Control Model Interpretation and decisions regarding sex are an integration of two separate processes 0 Excitatory o Inhibitory I In what way might inhibitory sexual processes be evolutionarily adaptive I Men who have erectile dysfunction have higher inhibitory processes than men without I Some of them have a problem because they have a medical problem amp some have psychological problems I Those with it because of medical reasons have lower excitatory pI OCESSES I Risk taking some people take more risks when it comes to sex Of these people who are women they have higher excitatory processes In men they have lower inhibitory processes 0 People vary in their predisposition to these processes amp these propensities are independent 0 These processes result from genetics early learning This model provides possible
