I just thought breast feeding gives real pleasure...?

You dont feel physical pleasure. It could feel relieving though if you are full. It could hurt for a week or so, but will go away unless you get a clogged milk duct. The more you nurse the more milk you will produce and it is by far the best thing for a baby. You can feed from both breasts, but you can also feed from just one if the other one cant for some reason. It is best to allow 15 mins on each breast, and alternating breasts when you start to feed. If you stared in the right side this time, start on the left side the next time. You can also try nipple cream which helps relieve the pain and is perfectly safe for baby. Dont give up!!
