New found desire [F25, M27] is this normal?

Recently I found out I love to be slapped during sex, I don’t know what it is about it but I love it. At first, it started with getting spit on and a light slap, but over the weekend I asked to be slapped and increasingly asked to be hit harder and harder and harder and hARDER.
It makes my whole body tingle just thinking of it; when I get slapped hard it makes me gush all over our sheets and cry with joy,
Is this normal? Haha
