Question

what is the role of women in copulation????​

Answer 1

Female copulatory vocalizations, also called female copulation calls or coital vocalizations, are produced by female primates, including human females, and female non-primates. Copulatory vocalizations usually occur during sexual intercourse and are hence related to sexual activity.[1] Vocalizations that occur before intercourse, for the purpose of attracting mates, are known as mating calls.
In primates, copulation calling is typically observed at the end of mating[2]and there are vast variations between species regarding its occurrence, frequency and form. It is agreed that coital vocalizations fulfill an evolutionarypurpose[3] and that they serve as adaptive solutions to problems that the females face, such as infanticide, as well as obtaining high quality sperm.[2]
In non-primates, copulatory calling predominantly occurs before copulation in order to attract mates (mating call). Calls vary in frequency (14 Hz[4] to 70,000 Hz[5]) and function. One of the main purposes of females vocalizing is the induction of mate guarding behavior in males.[6] Conversely, calls may also be used in order to attract high ranking mates who can prevent intercourse with the initial partner.[7] This is done to incite male mate competition.
In humans, coital vocalizations are linked to orgasm,[8] hence occurring during copulation and serving as an expression of sexual pleasure. Vocalizations can be used intentionally by women in order to boost the self-esteem of their partner and to cause quicker ejaculation.[9]
