hello, thanks for using healthcaremagic. When someone ejaculate so early that before female partner get orgasm, it is called premature ejaculation. As you are young counselling and behavioral changes approach can help I guess.As experience makes the man perfect, you will get control over your ejaculation as time passes.Don t worry for marriage , as performance anxiety can also cause such problem. In this situation you need sex counselling with anti anxiety medicines. Stop and squeeze technique and master and johnson technique can be learnt from qualified sexologist/psychologist. Another option is medicines like clomipramine which can be taken daily or sometime on required basis after doctor s consultation.Another medicine is paroxetine.So better to consult doctor for best option. Hope I have answered your query, if still any confusion late me know. regards, dr. Chintan Solanki
