You can try lots of soy in whatever form you enjoy, too. Personally, I like the soy drinks and soy pudding stuff. Soy contains phytohormones (that's herbal hormones) which to a certain amount may help fix minor issues with your period (helps me to keep it nice and regular). As far as food supplements are concerned, almost nobody lacks Vitamin C, and almost everbody doesn't have enough iron. Very common are also lacks in Vitamin D (because it is only absorbed in combination with fatty acids) and B. If you feel down at times I would recommend a high quality combination of all common vitamins. If it doesn't help, it won't harm. For access water you can also try nettle tea, works wonders and is entirely natural.

To return to the original question -- I'm on the same page with Amber, my period is usually no issue for me and neither is it for him, so if we (he) feel like it we go for it. I don't think, however, that sex, nakedness or anything between these lines is required to have a D/s dynamic going. There are other things that you can do, I for example like simply sitting at his feet, or running him a bath, or...I don't know, just little things -- he says, I do, and while this is possibly not the most orgasmic thing to do, it nonetheless reminds me of the way things work between us, even if life intervenes and we don't get to play as much as we would like. So maybe something like that might work when you are on your period and not feeling up to any purely sexual escapades? Just a thought
