Some employers stubbornly opposed efforts by their employees to form unions to collectively negotiate for higher pay rates, more benefits, and better working conditions.

During sexual arousal and sexual intercourse, the amount of fluid in the vagina increases due to engorgement of blood vessels surrounding the vagina. This engorgement of blood vessels increases the volume of transudate from the vaginal walls.  Transudate has a neutral pH, so increases in its production can temporarily shift vaginal pH to be more neutral.  Semen has a basic pH and can neutralize the acidity of the vagina for up to 8 hrs.
