I am wondering about the 2 string. It looks fun and sexy, but I wonder if its comfortable or not?

In some ways I imagine it to be more comfortable than a normal thong...

Not totally sure what you mean by 2 string. But I've tried just about every type of thong I've ever seen in a store. So far, my favorite is hanky panky. But since they are ridiculously expensive compared to say, target (my favorite place to shop), I usually settle for anything thicker than a string as I find the strings to be uncomfortable. But hey, everyone is different. I'd say buy one and try it out for yourself.

I am referring to the bracli thong, or the sensua thong.

The bracli thong goes for $49 for the single string and $59 for the double string, so it's a little too much just to experiment with.

Hm. Everything I found for the sensua thong via Google said it's no longer made by the manufacturer.

The bracli thongs look uncomfortable, but if you're wearing them just as lingerie right before sex, well, seems like you probably wouldn't be wearing it long anyway. For all day, I'm not sure I would be able to do it.
