We often forget about the biggest and most important sexual organ - our brains.
One way to enhance mental stimulation during sex is to make it a multi-sensory experience. Think about different textures and physical sensations, such as silk, linen sheets, feathers or close-breathing behind the ear. Think about maybe withholding sight through blindfolds or increasing mood lighting. Think about specific verbal cues your partner would enjoy or incorporating different scents into your play. On the one hand, our brains love to attach smells to memories, so we can associate particular colognes or candles to fun times; on the other hand, our natural body odors are strongly linked to sexual attraction and arousal in studies of compatibility, so keep that in mind when getting all hot and sweaty!
