my sex drive is higher during a period. but humans definitely are still caught up in the taboo that they are bad/shameful/need to be hidden. its a fact of life that all women experience from puberty to menopause and everybody should be somewhat educated and the eww reaction should be dead by now. seriously. the vagina is self cleaning if everything is normal down there and sex during a period is no different. i dont think a period opens you up to any chances of infections or issues.
