When I make out with my boyfriend I get really light-headed and sometimes I'll go blind for a few seconds afterwards what is wrong with me?

Feeling light-headed or experiencing temporary blindness during or after making out could be due to a few factors, such as hyperventilation, anxiety, or a sudden drop in blood pressure. The excitement or physical exertion might cause you to breathe rapidly, leading to decreased carbon dioxide levels in your blood. However, it's important to consult a healthcare professional to rule out any underlying medical conditions and to get personalized advice.
