Bend penis and erection dysfunction.

1. Penis bends downward when erects, around 1 inch vertical then bends downward. It does not become fully wide. 2. Need to use strength to push blood into organ to make it hard, and becomes weak when I release the strength. It does not stay hard. 3. Don't have a good urine pressure, I need to apply pressure on it. 3. Unable to get a full erection, erection happens only in half of the penis 4. At morning time if I sleep on my stomach and rub my penis genitally(this is how I used to masturbate) then sperms come out within 10S, but I last around 10-15-20 min when I masturbate in my bathroom, ( I am able to manage) but very weak erection. 5. My erection smells bad and the successive urinates which are after an erection. 6. I am 24 now and would get married after one year. Really have no idea how would I perform then and what sort of treatment should I go for. Never had sex with any partner. Please help me out.
