Horny levels around your cycle

Desiree
I know it will vary (probably), but I've heard that women get horny around or during their periods. I've never experienced this in my life until the past few days. My period will be starting later this week. (I'm finding it pretty insane but I'm sure I will use it to my advantage eventually ;) 
When, if at all does this happen for you? Before your period, during, or after?
