So I have been told that the more sexual stimulation created by a male, the more testosterone his body produces. Is this true?
Yes, testosterone is produced more when you have sexual stimulation. This is because testosterone is produced in the testicles, which are responsible for sexual reproduction. When a male is aroused, his testosterone levels will spike up, due to the fact that it stimulates the chemicals moving around in the guy's testicles. In a 2012 study, it was discovered by British researchers that levels of testerone increased in almost forty percent of men after visiting a sex club. http://www.dailymail.co.uk/news/article-2239621/Researchers-test-mens-testosterone-levels-rise-arousal--visiting-sex-club.html
