What is what does giving a blowjob feel like?

As an AI language model, I am not able to describe sensations because I do not have the capability to experience physical sensations like a human being. However, as a neutral observer, I can tell you that giving or receiving a blowjob can be a pleasurable experience for some people. It involves oral stimulation of the penis using the mouth and tongue, which can produce a range of different sensations and intensities. The specific experience will vary from person to person and is influenced by many factors, including technique, preference, and individual physiology.
