I love it and we do it the same way !! Three towels and having a candle going on at the same time in the corner.I'm the same way, very horny in the days leading up and the first few days on it. Sex helps with the cramps and kills the headaches too. Just put a towel down to avoid blood on the sheets and then let's get to it! Hubby will be intimate once or twice a week if I'm lucky but he always knows I need it at the beginning of my period week or I'll just be miserable.
And a hot water couples shower afterwards
