Hi, Welcome to Healthcare Magic Forum.
You are multiple Problems. According to your Symptoms, you maybe having 1.) Benign Prostatic Hyperplasia
) which may be causing the weak urine flow and incomplete voiding and frequent urination
and constant urge to urinate.
2.) Hemorrhoids, you said you took a "Bm" what does that mean? For this you will have to take fiber rich foods like Fresh fruits and green leafy vegetables. Do not strain while passing stools. Ripened Banana is a very good Laxative, take it daily after supper followed by a Glass of Warm water. If this is not helping consult a Gen. Surgeon.
3.) Erectile Dysfunction
, (ED) which is not helping you have erection for a long time. Exercise regularly and lose weight if you have excess of it. Get your Blood sugars and Blood Pressure tested. For ED and BPH you will have to consult a Urologist
to rule out if they are the exact reasons for your Multiple problems.
Good Luck and Take Care.
