How can I achieve taharah and become a good HAFIZ E QUARN?

Hazraath e Ulama Ikram, Assalamualaikum Warahmatullahi Wabarakatuh. 1. I am facing a problem with my taharah, often I hesitate to pass urine because of this. After passing urine, I try my best to see to it that the last drop of urine is out, then wash with water, after this I walk for a short while on the place where I stand, again wash with water and come out. I use only the INDIAN toilet. After coming out I find some small drops of urine passing out, if I wash it with water, there will be a pressure to pass urine again. Because of this reasons my Prayers(Namaz) have been missing. I am really ashamed to narrate my problem personally to an AALIM, because looking at my face they would be shocked to hear such problems from me, as I ALHAMDULLIALAH have a big beard and wear Sunna’h cap always. I have a desire to become a HAFIZ E QURAN, my elders and other Buzrugs also motivate me in this, but the problem of taharah is being a hurdle for this. ALLHAMDULILLAH about 4 years back I have even lead the tarawih prayers in our masjid(in Bangalore) for the last 3 days of Ramadhan. But then for all these good things taharah is becoming a hurdle. I feel I donot know the way to achieve taharah, rather than feeling it is a problem related to my physical health. I perform WADU for every Salah, suspecting there should be a problem with my physical health(i.e Drops of urine continously passing out). I strongly feel this problem is due to lack of knowledge in achieving taharah after passing urine. I would humbly request you to guide me to get rid of this problem and pray to ALLAH that my problem of taharah is solved. Please pray for me that I become a good HAFIZ E QUARN, follow the Sharia’h properly and become a good DAEE E DEEN. I am really sorry for having written my such big problematic description. JAZAKALLAH U KHAIRAH.
