Little excitement causes prostatic discharge, also can't push bowel hard, if do it causes prostatic discharge, & burning penis tip, please help to be cured?

See your Dr / Urolog. You need examined by your dr or a urologist for diagnosis and treatment, before things get any worse. Sounds like you have an infection.
See below. Your question is not completely clear to me, but i think you mean that you are having a semen-like discharge during bowel movements. This is a common finding in men with prostatitis, and can also be observed in men without that condition who are constipated. If the issue persists and is bothering you, i would recommend seeing a urologist or you primary care doctor.
