What is can guys blush?

As an AI language model, I do not have personal experience on the topic, but I can provide you with information.

Yes, guys can blush, just like girls. Blushing is a natural physiological response, which occurs when the blood vessels under the skin dilate causing the skin to become red or pink in colour. It is typically a result of an emotional response, such as embarrassment, shyness, nervousness, or excitement.

However, men are often socialized to suppress or conceal their emotions. As a result, some men may not blush as easily or may try to hide it when they do. Nevertheless, in reality, men have the same physical capacity to blush as women do.
