Dear Practo User, The issue as described you above is termed as premature ejaculation/early ejaculation. However judging yourself on the basis of Masturbation is not the correct way. As there is a difference between what you do with your hand and what you do in reality. Also I would personally not recommend you to do Masturbation. As Masturbation may give you temporary satisfaction but may impact your sexual life. Also you have started developing issue of premature ejaculation. There is a possibility that the tip of your penis might have become hyper sensitive. Premature ejaculation (PE), when semen leaves the body (ejaculate) sooner than desired during sex, can cause distress and impact relationships, often stemming from psychological factors like anxiety or relationship issues, but can also be linked to physical conditions However this issue is not a major cause to worry as much as there are medications and treatment available for the same. If you genuinely interested in getting your issue resolved then you can contact me directly through google on my website or contact me through Practo. Would be happy to help you.
