Hello
Thanks for using DoctorSpring.com for posting your query.
I have gone through your question in detail and I can understand what you are going through.
The condition that you are suffering is called premature ejaculation. Now its a type of anxiety disorder and the person normally suffers from performance anxiety where in he is anxious if he can perform or not. The ED starts as a result of anxiety, it can be treated.
First you can try the start stop technique. Your partner is supposed to start stimulating you and the moment you are about to ejaculated she is supposed to stop all the stimulaton and and hold your penis head hard. Now this should be repeated.
Perineal exercises also help but it seems they have not helped in your case.
One solution is medications. Some patients are not willing to wait for these acts to produce results and instead demand medicines. I prescribe them 12.5 mg paroxetine at night and they are doing good. Normally one should try until 25mg of Paroxetine. If paroxetine is not effective then Dapoxetine is an option. It has to be given 1 hour before having sex and will prolong the sexual interval.
There is no sureshot immediate cure but with time this problem settles down
Hope this helps,
In case if you have any further query, do let me know.
Kind regards
