I couldn't/wouldn't use sponges, and never work during my period. But I have to say, this month I am really gnashing my teeth: I've turned down so many genuine-sounding blokes that I could have had my best week in ages. It's like I'm emitting a pheromone that's attracting half the men within a 30-mile radius.
Of course, sod's law dictates that come the weekend when I'm back in action - tumbleweed...
Roll on the menopause?!
