Hi, I Am 22 Years Old Man. Urine Still Drips

Hi,
I am 22 years old man. Urine still drips after urination. Often get gas (farting) hard to control. When masturbating; its somehow slow. It itches inside balls and penis after ejaculation for a litle while (taking bath and washing the area helps). Stools are sometimes like diarhea, sometimes like swampy, sometimes I just see food coming out as I ate it (a whole mushroom bite, a line of tomato etc. , sometimes also beltformed stool.

I wonder if you can help me with this
