Sensation play is a great way to engage all of your senses in sensual play. From physical pleasure to food to smells, there are a lot of ways to involve the senses in your sex life. Sensation play is often used in BDSM with elements of pain play. Sensation play can also be gentle. It is all up to you and you are only limited by your imagination.

TOUCH

For the touch side of things, you could use different fabrics like silks, cotton, Terry cloth, leather or other textures. Feathers can provide a pleasant sensation aside from just tickling. Switching between these can serve to create different sensations. Ice or heat are other popular options of switching between opposite sensations. Breathing against the skin or licking can be incredibly sensual. Tickling and massage can get the blood pumping and make the skin more sensitive. Fingertips or light nail scratching can feel great also.

SIGHT

As far as the sense of sight is concerned, you can use blindfolds to heighten the other senses. Being without sight can make you concentrate on your other senses. You can use erotic pictures or movies to get in the mood. You can also do a strip tease or dance for or with your partner. Watching each other touch themselves can be an erotic experience. There is a reason porn is so popular! We often begin arousal with sight. Attraction on a visual level is important. Looking at our partners in a sensual light is often times the first step to a sexual encounter, whether it is the first time or a part of a long term relationship. 

TASTE

Taste is a very sensual sense that should be brought into sensation play. Food and drink can be tasted either on their own or off of your partner. You could even eat foods that have aphrodisiac qualities to intensify the effects. Licking chocolate or whipped cream off each other is sensual for both partners. Trying sweet or spicy foods, perhaps while blindfolded, can add some pleasant sensations to your play. A meal or a snack can be had before, during, or after your sexual play.

HEARING

Sound can be moving. Music often helps set the scene for sensual play. Make a Playlist together of songs that get you in the mood or build up your excitement. You can also whisper either sweet nothings or dirty talk, whatever does it for you and your partner. Communication is more than just consent and instruction. Talking, whispering, and even moaning can communicate your desire and enjoyment to your partner. Talking out what you want to do or have done to you can be an erotic act all on it's own.

PAIN

On the BDSM side, pain can be a powerful sensation. Light spanking to more intense scenes can produce pleasure in both partners. Flogging, spanking, and texture play can be used. Sensory deprivation can also be used to heighten sensuality. 

Sensation play can encompass all the senses or focus on just one. Play around with your senses, and your partner and reap the sensual rewards.
