Erectile dysfunction , premature ejacula

I m suresh from delhi. Age 29. Never smoke, never drank alcohol, no pan gutkha, very rarely ate fast and fry food, always ate healthy.. Juice fruits etc. Also physically active... Sometime I go to gym.. Sometime racing... Walk around 6-7 km daily. No non veg except egg. 10 yr back when I was in school I had nightfall almost daily and twice thrice a night.. I never told parents bcoz of hesitation. At nights I felt sensitivity or itching at penis forehead, my hand went their unintentionally and rub it using fingers very hard. Sometimes it hurts while urinating. Over the time this continues. Also I coould not pull back forehead skin. Its yet not treated. Sex was very painful with this. 4-5 years back I felt loosing erection especially penis head is becoming soft. I dont get a boner in morning since last 3-4  years. Though while with my gf I have erection but it's 50% and erection stays for very low time. I m facing premature ekaculation also since these 3-4 years.
