Position Support and Enhancement
The most popular position support for couples is a pillow and you can use any pillow for that.
However you can splurge and buy a special sex pillow that usually has a sturdy foam inside and removable cover.
Another type of position support are sex slings that allow to hold legs suspended in the air for better penetration.
For more experienced couples the sex swings might become an ideal addition to their lovemaking.
They are great for stand up sex and provide possibilities for endless variety of positions.
