This literally is about the easiest sex tip to introduce into your sex-play and that really builds sexual tension.
Use a feather (available from High street adult shops, arts and crafts stores and even home furnishing departments!) along with massage oil to bring their skin to life.
The setting: you've been enjoying foreplay and your partner is lying back. Have the massage oil and feather to hand so you can drizzle a little oil along their breasts, over their stomach or down there thighs.
Then kneeling beside them trace lovely swirls and squiggles with the feather through the oil.
Use the tip of the feather to then circle their nipples - men also respond to this. Feathering feels amazing - enjoy!
