Although period sex may no longer seem like such a taboo, there is still a lot to know about getting it on when you have a flow. And sure, period sex is in no way dirty, but the weird things that happen when having sex on your period may take you by surprise anyway. Fortunately, most of these are good things.
Aside from the simplest reason of all — you just want it — period sex can provide you with a ton of unexpected benefits. It may help alleviate your aches and pains, and it could also shorten the duration of your period overall. Plus, there's no denying the power of orgasm to take your mind off of pretty much everything for at least a few minutes.
That said, if you'd prefer to chill out with a heating pad and a cup of tea, then that's fine, too. Even during your period, sex is an option, but it's never a requirement. Taking a pass, especially on those heavy flow days, is understandable.
But if you are interested in sex during your period, then there is almost no reason to forego it. As long as you're taking the usual precautions to protect yourself from unintentional pregnancy or STIs, then it's go time for you and your partner. Maybe you won't dislike that time of the month so much anymore.
