This is a very touchy and personal subject for many people, but it need to be watch very careful by anyone who like to walk on spiritual path.
Sexual activity performed with a negative intent or motive is impure.

Menstruation is used by the vital body to evacuate residual negative energies and toxins from the body, and as such women should not touch ritual items or sacred objects during this time. And most important don't sleep with your woman if she menstruate.
Sex can be a sacred act, or it can be bestial, and depending on the state of mind the spiritual results will be given.
