Summarize the following:
Some doctors believe that finishing prematurely may be the result of personal problems or bad habits developed in past experiences, both in your current relationship and in previous ones. By identifying these possible trouble spots, you can better work through them with your partner or a therapist. Some problems from your past could include hurrying to climax in order to avoid being discovered or rushing through sexual encounters to avoid guilt. Talking to your partner may also demonstrate that you have nothing to worry about. Your partner may not find anything wrong with how long you last. At the same time, your partner may also have some ideas for new positions and foreplay that can increase intimacy and passion, as well as the length of time.
Think about psychological difficulties. Talk to your partner.
