"Male sexual arousal may proximately cause the deployment of sperm competition tactics. Men’s
pornography preferences provide insight into male sexual arousal because pornography is produced
largely to facilitate or enhance male sexual arousal (Mosher, 1988). Therefore, more sexually arousing
pornography is likely more popular and prevalent. Pound (2002) documented that MMF pornography
(i.e., indexing sperm competition) is more prevalent than male-female-female (MFF) pornography (i.e.,
indexing the absence of sperm competition). These findings are consistent with men’s reports of their
preferences in pornography (Pound, 2002; cf. Hald, 2006). McKibbin, Pham, and Shackelford (2013)
found that the frequency of images on adult DVD covers depicting MMF pornography predicted the
DVD’s sales rank, whereas the frequency of images on adult DVD covers depicting MFF pornography
did not predict the DVD’s sales rank. Consistent with findings from Pound (2002) and from McKibbin et
al. (2013), men produce more competitive ejaculates when viewing MMF pornography than when
viewing FFF pornography (Kilgallon & Simmons, 2005).
An alternative explanation is that men prefer MMF pornography because they are super-
stimulated by witnessing simultaneous, multiple, sexual acts (e.g., oral sex, vaginal sex). However, Pound
(2002) and McKibbin et al. (2013) found that MMF pornography was more arousing than pornography
depicting multiple males and multiple females—scenes which likely contained the most frequent
representation of simultaneous, multiple, sexual acts. Thus, men likely prefer MMF pornography because
of adaptations to sperm competition, and not because of male hypersexuality.
Male sexual arousal causes behavioral and physiological adjustments that may function as sperm
competition tactics. For example, men who are more sexually aroused express greater copulatory interest
(Ariely & Loewenstein, 2006) and produce more competitive ejaculates (Zavos, 1985; Zavos &
Goodpasture, 1989). Furthermore, men who are experimentally sexually aroused report a greater
likelihood of performing sexually aggressive behaviors (Ariely & Loewenstein, 2006). Because men are
sexually aroused when viewing sperm competition cues, and because their sexual arousal causes
deployment of sperm competition tactics, assessing men’s sexual arousal provides insight into human
sperm competition psychology."
