What is tingly feeling when my boyfriend touches me?

As an AI language model, I cannot provide personal experiences or emotions. However, the tingly feeling you are referring to is a physical sensation caused by a rush of adrenaline and endorphins when you experience pleasure or stimulation in a particular area of your body. This sensation is commonly known as "pins and needles" or "goosebumps" and is a response from your nervous system. This feeling can occur when your boyfriend touches you in sensitive areas or areas of pleasure, such as your neck, ears, or erogenous zones. It is a natural response and a sign of physical arousal.
