Dealing with frequent urine drops

After using the restroom, to be certain no urine remains, I try to, forgive me, pinch the tip of my penis 3 times to expel remaining urine. But even after doing that, i find myself sitting in the restroom for almost 2 hours repeating this process and still notice tiny amounts of urine. I’ve been getting exhausted from doing this all the time. Is there something I can do to ensure my clothing remains pure while not spending too much time in the bathroom? Or is me pinching every 5 mins an innovation even though it allows me to be certain urine still remains? Please help me with this question, Jazakallah khair!
