Hi doctors. I tried everything like deap breathing, stop n start techniques, mind ejaculation kegal excercise, but nothing cure premature ejaculation?

Lidocaine spray. There are over the counter treatments to help. The most popular is a Lidocaine spray you can buy over internet.
SSRIi meds. I trust you also tried the squeeze technique. if a Ssri like Zoloft (sertraline) prescribed by your physician does not work, I will be very surprised.
