Editing Orgasm (section)

==== Two-stage model ====

The traditional view of male orgasm is that there are two stages: emission accompanying orgasm, almost instantly followed by a refractory period. The refractory period is the recovery phase after orgasm during which it is physiologically impossible for a man to have additional orgasms.<ref name="Morrow">{{cite book |author = Ross Morrow |title = Sex Research and Sex Therapy: A Sociological Analysis of Masters and Johnson |publisher = [[Routledge]] |date = 2013 |page = 91 |isbn = 978-1-134-13465-6 |url = https://books.google.com/books?id=wqG07-UF0yoC&pg=PA91 |access-date = April 15, 2019 |archive-date = February 27, 2023 |archive-url = https://web.archive.org/web/20230227055216/https://books.google.com/books?id=wqG07-UF0yoC&pg=PA91 |url-status = live }}</ref><ref name="Carroll, Refractory period">{{cite book |author = Janell L.

Masters and Johnson state in the first stage, "accessory organs contract and the male can feel the ejaculation coming; two to three seconds later the ejaculation occurs, which the man cannot constrain, delay, or in any way control" and in the second stage, "the male feels pleasurable contractions during ejaculation, reporting greater pleasure tied to a greater volume of ejaculate".<ref name="Dunn">{{Cite journal |author = Dunn ME, Trost JE |title = Male multiple orgasms: a descriptive study |journal = Archives of Sexual Behavior |volume = 18 |issue = 5 |pages = 377–87 |date = October 1989 |pmid = 2818169 |doi = 10.1007/BF01541970 |last2 = Trost |s2cid = 13647953 }}</ref> They report "for the man the resolution phase includes a superimposed refractory period" and "many males below the age of 30, but relatively few thereafter, have the ability to ejaculate frequently and are subject to only very short refractory periods during the resolution phase". Masters and Johnson equate male orgasm and ejaculation and maintain the necessity for a refractory period between orgasms.<ref name="Dunn" />
