Why are womens sex drives stronger at that time of the month ? And that seem unwarranted?

Do you still have intercoure , do you masturbate or do you keep on?Why are womens sex drives stronger at that time of the month ? And that seem unwarranted?
i know. it's so unfair.
i other get turned on really glibly when i'm with my bf, or next to a Sexy guy. but then i seize really in the mood and get the impression like ripping his clothes rotten, but i can't because of my period.
i masturbate. & beside the guy if possible. we still do sexual act but not intercourse for obvious reason.
well, my cousin still have sex during the time of month. she says it help cramps... wow, lol but i have realize that sex drives are longer and if my boyfriend were interested to having sex i would. its fluent, even if ur on ur period. so if u grain like have sex go for it.
hah! its because our sex hormones are crazy and up at that time...though some women are surrounded by too much pain to even give attention to about it.
