hi, thanks for writing ..i have understood your concerns. when a person masturbates there develops a conditioning in which person is used to ejaculate early because of frequency of stroke and stimulation during masturbation.. thus person is used to ejaculate early. but this is not a big problem.you just decrease the frequency of masturbation, you will be alright.. if you continue to have early ejaculation after marriage then you shud consult a sexologist. there are behavioral techniques available which can delay ejaculation without taking any drugs and the effects are long lasting.. drugs are also available, they are SSRI antidepressant medications which causes delayed ejaculation as a side effects.so they are useful for the treatment of premature ejaculation. in my opinion you shud consult a psychiatrist only if your problems continue after marriage. at present you shud not worry just decrease the frequency of masturbation. i hope this will be helpful to you.. best of luck..
