Is it normal to use sex delay creams or sprays ? or there are other ways to overcome premature ejaculation ?

"Normal" wrong Q: Is it reasonable, yes. Does it help resolve premature ejaculation cause, not really, but it aids with the problem, and does not have much of a downside, so would not worry about it. Real solution comes with practice at pacing / not over-stimulating yourself too quickly and self-control. Good luck.

Stop-start: One of the main psychological techniques for premature ejaculation is the stop-start technique. When a man feels that he is getting close to ejaculating, he either slows down, pauses, or changes position. There are also medications that may help and there is couples therapy.
