👉 Bondage veins are small, red or purple veins that appear under the skin of people who engage in bondage activities. These veins are caused by increased blood flow to the skin and muscles during sexual play or bondage. Bondage veins are often found on the arms, neck, and legs, and their appearance can vary from person to person. The presence of these veins is not necessarily a sign of sexual arousal or activity, but rather a physiological response to stimulation.
