I am a male biologist.
Hmm. your situation reminds me of female primates (except humans). See, for
example, Domb LG and Pagel M, Sexual swellings advertise female quality in
wild baboons. Nature, volume 410, pages 204-206 (8 March 2001)
("The females of many Old World primate species produce prominent and
conspicuous swellings of the perineal skin around the time of ovulation.")
