I am having an errection problem i ejaculated within 1-2 mins, even the erection is not hard, few weeks back when i was about to have intercourse with my partner and i was wearing condom i ejaculated during that time and coudnt proceed, few week later when i again tried it during foreplay i had an errection but the point when i was ready for intercourse my errection was lost & even if i have errection during masterbation it does not last longer. Even the foreskin of my penis is too sensitive, it is so sensitive that even if i touch it pains.
