Since the age of 13 to 17, I was maturating almost daily. But after that I lost interest and left this habit, but after that, I started to suffer from severe nightfalls almost 4-5 days in a week. This is still in progress. Now am 26. I will get proper erection while sex, but sperm is getting ejaculated during foreplay itself while having sex with my gf. If somehow I manage to control, I am unable to penetrate inside vagina Bcs as soon as I keep my penis near vagina, I get ejaculation. I am really worried. My weight is 72 kgs and height is 175cm. Please suggest. I am unable to see my future as a good husband.
