If you are a guy, and your testosterone n men, higher levels of testosterone mean you are more likely to have sex, want sex, and want to watch sex.
Men who watch porn, were shown, in research settings to run testosterone levels about one third higher.
After a guy watches a sexually explicit movie, his levels peak at about a third higher than they started, and the testosterone peak will come about 60–90 minutes after the end of the film. Sexually neutral films do not elicit changes in testosterone levels.
Watching porn, or what is termed in research settings, to be sexually explicit films have a boost in overall motivation, competitiveness, and decreased exhaustion, and are likely to report better game day performances!
Those men with testosterone deficiencies cannot respond to these normal cues as well as a male with normal levels. Hormone optimization works for both males and females!
