Period sex opinions?

So me and my boyfriend have had sex 3

Times while I was on my period first two

Times it was my last day so it wasn’t bloody ya know... but this last time it was the second day. It was the best sex we have ever had. Usually he is great and always makes me feel good but that last time was the best thing ever and we didn’t just go once we went 3 times which was new for us too. We just couldn’t stop. If it a “thing” for sex to feel better when you are on your period? Tell me how it’s been for you!
