I've searched twice for "bloodplay" and "blood_play" tags but only one image came up under bloodplay. And it hardly involved blood play but that's not the point.

I like these images a lot and want to find a tag to use should I start making my own. An example of what I'm talking about when I say blood play is postID: 261608

Basically using blood when preforming sexual or somewhat sexual actions. Kissing is the most common in that scenario.

What kind of tag and or tag(s) should I use to find these images in the future or tag my own work when I finally get off my lazy ass and make some.
