I am male 29 and got married 1.5 years ago. Since day 1 while having sex with my partner I have suffered from early discharge. We do have decent foreplay sessions before intercourse but while I penetrate my partner the head of my penis tickles/feels very sensitive and makes me discharge within 3-5 seconds. I do have a good erection and also apart from the time of penetration, I do not feel any ticklish/sensitive. I feel ticklish only when my penis is in an erect state. Also please explain the treatment details and cost of medicines.
