Fen shui, the Chinese vasthu silpa has a lot of tips for couples to spice up their bedroom life. It advises to have the bedroom with no extra stuff in it. No TV or computer or anything of such ...! Only a neat and clean bed with proper bedsheets (preferably satin sheets) with suitable colors.
The bed room must have ample oxygen flow. There should not be any plants or such things unless it is too large. No pictures or photos that spoil your mood. Playing some soft and romantic music at the background will improve your and partner's sensual mood and will help in your performance.
Have many Happy and enjoyable times in your bedroom...!
