I recommend that you visit a urologist to discuss your premature ejaculation and erectile dysfunction problems.

I don't recommend use of tadalafil without prescrition from a doctor. And if you are not diagnosed with any sexual dysfunction, it is not good to use medications. Tadalafil is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. Only a qualified doctor can make an accurate diagnosis and prescribe the best treatment for you.

The urinary tract is the part of the body where the bacteria have entered and UTIs are the result. The main symptoms may include frequent urination, pain or a burning sensation while urinating, and urine that appears cloudier or even blood-colored. You need to take sufficient water regularly and the prescribed antibiotics till the end as instructed by the doctor. If the symptoms stay on then a different antibiotic might be necessary for your treatment or a further examination can be performed.

Phimosis is a condition where the fore­skin on a boy's penis becomes too tight and won't re­tract. It can make urinating tricky, trigger swelling, or cause­ pain. Usually, it stems from the foreskin failing to stre­tch properly during growth. Often, circumcision solves it – that's a simple­ surgery removing the ove­rly-snug foreskin. Getting medical he­lp is crucial if you or someone you care about face­s these issues.
