Why is my post-puberty penis still small?

It is essential to deal with any worries about your testicular health with care. If you are feeling pain, swelling, or noticeable changes, these might be due to different reasons, such as infections or injuries. Practicing good hygiene and wearing adequate underwear can help in this regard. On the other hand, if you have symptoms that remain or you are not sure about something, it is very important to see a doctor. A healthcare professional could do a complete check-up and give you appropriate advice for your condition. 

If you're experiencing erectile dysfunction—difficulty getting or maintaining an erection—it could be due to issues like blood circulation problems affecting your penis's length and quality. Stress, anxiety, and conditions such as diabetes can also affect your sexual health. To improve your situation, try reducing stress, staying active, eating healthily, and consulting your doctor for guidance. 

It's usual for people as they mature to have trouble obtaining and preserving an erection. This may happen because of reduced blood circulation, specific medications, stress, or fundamental illnesses such as diabetes or cardiovascular disease. To improve your condition, try remaining physically active, eating well, managing stress, and talking to your doctor about possible remedies.

If your partner has a ye­ast infection, you can catch it too, although it's not contagious like the flu. Yeast infe­ctions aren't sexually transmitted dise­ases, but intimate contact can spread the­m. Common signs are itching burning sensations, and strange discharge­. It's wise to abstain from sexual activity until your partner re­ceives medical tre­atment.

Frequent masturbation is a normal and healthy sexual behavior for many. It doesn't cause any significant harm or affect your future sex life. However excessive masturbation can lead to physical and emotional health problems, such as fatigue, anxiety, depression, and loss of interest in sexual activity. You can try to redirect your sexual energy into exercising or hobbies, and establish healthy routines and sleep patterns. 

The abnormal areas may manifest as sores, difficult discharge, pain, & itching of the private parts. These STDs are caused by bacteria or viruses that are transmitted through sexual intercourse. In case you think you might have an STD, you should go to a doctor to get tested and treated. Also, you should always protect yourself by practicing safe sex.
