when i masturbate i ejaculate very early nearly 5 to 10 min...

i just red some topic how to increase timing. but when masterbuate early the sex feeling at early stage is not same when i try to stop ejaculation when the feeling ends the again start masterbuating and so on for long time but when at last i could not control and i cum the sex feeling before cuming is so high but during cuming the felling is not as same as when i cum earlier...

plz reply..........
