Thank you for asking. Before considering a condition of Erectile dysfunction, it must be ensured that you are getting sufficiently aroused, you are able to get adequate stimulation, and there is no other problem of anxiety and stress, in absence of these issues only can a condition of ED be diagnosed. In your age group anxiety and apprehension pertaining to Erections, sexual performance, etc are very common. The short time to ejaculate, in your case, could be due to anxiety. More so, there are various myths and misconceptions seen in your age group regarding sexual facts, which must be clarified, and often causes fear and anxiety pertaining to one's sexual ability to satisfy a prospective partner. Considering all this, I would suggest you to consult with a sexologist in detail. A more information and specific questions could be asked by him to know more about the problem. Overall, I don't see an ED but an anxiety issue, which could be causing early ejaculation issue. Use of pornography, masturbation habit, sexual. Fantasies, are some important areas explore.
