Temperature play can be incorporated into strap-on play if you're using a dildo made from a material that can safely retain heat or cold, such as glass or metal. To engage in temperature play, warm or cool the dildo in a bowl of water before use, ensuring it's not too hot or cold to avoid discomfort or injury. Remember to always test the temperature on a less sensitive part of your body, like your wrist, before using it on more sensitive areas.
