I've seen a lot of posts of people asking if sex helps with cramping...well it helps for me!  Even if it's just me making myself orgasm. I know someone's going to say EW you touch yourself while you're on your period well I wear tampons so I'm always clean! So trust me if you're curious and in the mood and your cramps are also hurting like f*** go ahead do it. It honestly helps. You might have to orgasm a couple times ( depending on how big the orgasm is) but the feeling of those muscles tightening  and then releasing really helps with the cramps and it feels great.
