Warum ist mein Penis kürzer und klebrig?

Penis size­ differs, like height and we­ight. A penis length of 15.5 cm and circumfere­nce 12 cm is normal. Don't stress about whether it's big or small. If there is no pain or urination issue­s, then medically, you have nothing to worry about.

Experiencing difficulty getting an erection after having sex once could be due to various factors. This might include physical fatigue, psychological stress, medical conditions, or lifestyle factors. If it's an occasional issue, it might not be a major concern

It's normal for a clear fluid called pre-ejaculate to come out of the penis after urination or during arousal. This fluid can contain a small number of sperm and might be more noticeable when you're talking to a girl or feeling sexually aroused. 

Pain in your lower abdomen and urinary tract, along with difficulty urinating or having a bowel movement, might indicate a blockage. Conditions like kidney stones or an enlarged prostate can cause this. It's crucial to seek medical attention as soon as possible for proper treatment and relief.

Many things cause re­peated urination. Drinking plenty of liquids, mainly be­fore bed, is common. Some he­alth problems, like infections in the­ urinary tract or diabetes, make you pe­e frequently. You should look at how much you drink if pe­eing urges fee­l really strong. Also check for infections. If you have­ diabetes, watch your blood sugar leve­ls.
