Detailed Answer:
Hi

Thank you for asking Health care magic forum.

I have gone through your query. Certain degree of curvature in penis is accepted as normal. But if this curvature causes shortening or there is band like formation or pain during intercourse then you should consult an urologist to rule out peyronie's disease. An ultrasound of penis gives confirmation of diagnosis in such case also. In such case physical therapy may benefit also.

Physical therapy like manual stretching technique is helpful in some. There are various traction devices which can be applied also. But these should be done by the advise of an urologist.

For increasing stamina you can take food like eggs, meat or chicken , sea foods , various nuts like almond , hazzelnut and citrus fruits. You should also have regular exercise. Body building exercises are very helpful in increasing stamina. Taking Vitamin E for short periods intermittently also is good. Including fenugreek in your diet is helpful also.

For premature ejaculation you can try squeeze and stop technique, thought changing when nearing ejaculation or using condom with anesthetic. If this is not helping then approach a sexologist or psychologist for behavioral therapy. If that is also not helping then medications like dapoxetine prior to intercourse helps.

Hope this may help you. Let me know if anything not clear.
Thanks.
