Online, yes. I’ve made a few videos on the topic based on fan suggestions:
None of them show any menstrual blood though, because its against clips4sale & pretty much every payment processor’s terms of service. Which I think is ridiculous. Its perfectly okay to sell gang bangs & bukkake, but seeing a woman’s period? Why that’s obscene. The few sites that cater to it, as far as I know, are foreign.
I think the idea is really hot, because like most every other woman in the US, I grew up believing that my period was the grossest most disgusting thing about being a woman. For someone to be sexually aroused by it is arousing to me. My husband isn’t INTO it per se, but he’s gone down on me while on my period without a tampon in a few times (when it wasn’t too heavy) and I really like it. I’ll have sex on my period, just not when its too messy.
