Sex on your period.

S.
I've only ever had sex on my period once. And it wasn't planned. But it was amazing. Probably the best sex I've ever had.
 But I woke up today super horny on mine but my current "partner" We haven even spoke about it. How do you slip that into a convo to see if a guy is willing to have sex while you're on a period?
I know I could easily do it myself. But it's not the same. Lol.
