I was looking up the condition commonly known as “blue balls” (you know, because I could) and found this little gendered bit on Wiki:
Homologous condition in women
Women can also experience discomfort due to unrelieved vasocongestion as their pelvic area also becomes engorged with blood during sexual arousal. They can experience pelvic heaviness (aka blue walls, blue labia, blue box, or blue curtains) and aching if they do not reach orgasm. The general term pelvic congestion refers to such pain as it occurs in either sex.
I’d never heard any of these but have argued for years that women can, indeed, experience something akin to what guys describe as blue balls. Turns out I was right.
