Sperms are immediately released on masturbation, small penis. Treatment?

Hello,
Thank you for your query at DoctorSpring.com
Penis size varies from person to person and depends also on the state of erection. A person requires a minimum of 1 1/2 inch of penis to satisfy a woman. Anything beyond this is an add-on and wont help satisfying woman further as its only the outer one third of vagina which is sensitive for sexual stimulation. Rest of the vagina is not sensitive for sexual stimulation.
If your erect penis size is more than 1 1/2 inch then you need not panic. Yours is 4 inches and hence it shuld not matter. Further the reduced penis size can have multiple reasons and common one are low testosterone or low growth hormone or low thyroid. This can be assessed by doing blood tests for thyroid, testosterone and growth hormone levels. If any abnormality is found, the same needs to be corrected.
Its surgically or medically not possible to increase the penis size. Very sorry if it has disappointed you. But if there is a hormonal issue then it needs correction and the size of the penis will grow.
Regarding the issue of early ejaculation, 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.
First you can try the start stop technique. Your wife 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. These are the muscle exercises that occur when you contract the perineal muscles like when you are trying to stop the urine or feces. You have to do this contrations repeatedly daily to tone up the perineal muscles.
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 doubts, let me know.
Kind regards
