Hi Premature ejaculation can be due to anxiety, a new relationship , prior sexual issues or infrequent sex. Engaging in foreplay, diverting your mind during intercourse and increasing frequency of sex helps. Start-stop technique can be learned. Using a condom also helps. If these don't work consult a urologist who will prescribe some medications till the enhanced sensitivity gradually decreases to normal. Good luck.
