copulation and/or rejection of courtship by the male) also supports the sexual con ict scenario. We suggest that our ndings support the idea that the female prolongs the period of sexual activity to induce her partner to guard her (which reduces sexualcoercion from other males) and to monopolise his
intruding male's sexual competitor. Rates at which males received counter-challenges were calculated by dividing the number of counter-challenges a male received by the number of intrusions the male performed. Smuts & Smuts (1993) provide a definition of sexualcoercion based on a combination of behavioural
as a consequence of persistent mating activity. In a recent paper, Head & Brooks (2006) found no effects of increased sexualcoercion on fitness of female guppies. They measured female weight gain, gestation time, fecundity and offspring size and survival as parent and offspring fitness components
-standing repertoire of binary sexual complementarity. The naturalisation of male sexuality as inevitably intrusive is patent as the author notices how her informants struggle to see themselves as victims of sexualcoercion, sometimes simply because their partners affect caring behaviour outside the bedroom.
