18M, 50kg, uk born ethnically Pakistani, don't take any medicine, don't smoke, don't do drugs, virgin. For a very long time when urinating my stream would get weak near the end and then stop without getting all the urine out, a small stream remains that I have to shoot out by contracting, it takes about 7-15 minutes (it varies within this range) for urine drops to completely finish, so non come out or remain within my privates after urinating, hours after urine tiny drops of urine will come out via my privates touching my pants, not all at once, it is spaced out.

After urinating, once the drops stop coming out completely, I will squat and remain in that position for about 30 seconds to see if anything comes out, nothing does until hours after

I also use the technique where you press on the area behind the testicles with your fingers to remove excess urine

The I have done 2 blood tests that have came back fine and 2 urine samples that had were fine and also had an ultrasound done on my testicles as I also have an issue of releasing penile discharge with no arousal throughout the day

Does anyone know what could be wrong with me?
