@Poshi: Hm, maybe it isn't the vaginismus then. Either way, I think it would be okay to talk to a sexologist and maybe they would be able to figure it out.
period talk (my fave 8D lol): I would be slightly scared to use the cup... I actually like tampons, but can't use them. I don't have that big of a flow so changing them is painful, since they don't suck enough blood throughout the max 4 hours (I think it was? someone correct me plz?). But they just... clog me up...

And it hurt me more, and the pain lasts longer. And I don't need any additional pain, I'm already dying frequently enough. If my period isn't too painful one month, I'm SUPER lucky. I need perscription painkiller to get rid of the pain, and sometimes even that only dulls it.

So, I like tampons, because they don't leave the damp feeling or anything. But because they clog me like that, I get worse cramps and sometimes they can last even through the whole period and beyond. So no, thank you. I'm done. I rather feel like having a diaper

At least we have the pads that don't feel like it. ... Too much
So I would be scared a cup would feel similar to tampons for me.
