Iam 31. I have got married 2 years back (Aug 28 2006). Yesterday, erection was there. But it is not long lasting. During intercourse, my wife felt pain. After 3-4 minutes of intercourse, we sopped. Sperm is not released. After that, we slept. Whether we have to continue for much longer time ?Any food habits to follow to improve erection and sperm count and release ?
