Generally, 21-year-old guys can have varying facial hair, from full beards to barely any growth. Don’t worry if you don’t have a beard yet. Your body may still be developing, which can affect facial hair growth. Hormones play a big role in this process. By eating a balanced diet, exercising, and getting enough sleep, your hormone levels can remain balanced, supporting beard growth. If you have concerns, it’s always a good idea to consult a dermatologist.

The boil-like structure could be a symptom of an infection. Pain and irritation while urinating are the most frequent. These include antibiotics or antifungal creams to help with the infection.

It seems you might have an issue such as balanitis, a common and naturally occurring thing among men. It can be seen in a small mole-like structure on the tip of the penis that is occasionally pus-filled, and it could get inflamed and red. It could also be connected with the frequency of penis washing, or it could even be traced back to some personal hygiene habits or yet another significant thing like any irritability that might be caused by soap or disinfectant. Frequent washing and drying of the area are key to a better outcome. The application of mild soaps and the avoidance of harsh chemicals are also helpful strategies. Wearing comfortable, breathable clothes and underwear made of cotton is also good. Wear only loose-fitting clothing and wear underwear made of soft, comfy cotton. When all else fails after a week or two and the results don't get better, it is a good time to see a dermatologist, possibly for further evaluation or to control the underlying issue.

The pimples on your skin grow when the oil glands get blocked. Your first step in resolving this issue is keeping good personal hygiene by showering daily and using the right soap to suit your skin.

On the other hand, wearing roomy clothing will let your skin breathe, hence you will not have the problem. For the people out there who need them the most, they likely don't even feel comfortable asking you for that so the effect would be squandered. If these steps don't work, visit a dermatologist.
