Hello,
Welcome to HCM,
Pre-mature ejaculation is the commonest sex problem through out the globe and commonest cause is
anxiety due to fear of not satisfying the partner, fear of being seen, fear of losing hardness and a lot of other myths.
One may have anxiety related to sexual performance only or to each and every thing going around. I suggest you to try to relax , refocus more on the enjoyment of being together than on the time spent after penetration.
I can suggest you to follow
1.Try to analyze what makes you anxious that is the thought responsible for it.
2.Take your wife in to confidence and reduce the weight of expectations by yourself as well as your wife.
3.Start on breathing exercises- take a deep breath and try to breathe out as slowly as you can . Repeat as many times as possible.
4.Kegel's exercises- Tighten your pelvic muscles, take a deep breath, hod for 10 seconds and slowly release. repeat as many times as you can.
Thank you.
