More details needed

Detailed Answer:
Thanks for using the Ask a Doctor service.

I have gone carefully through your query and understand your concerns. There are a number of things that I need to mention.
* You need not avoid sex if you wish to avoid pregnancy. Contraceptive methods like OCPs and condoms can help you avoid pregnancy. However, that does not seem to be concerning at the moment.
* It is not impotence if have been able to masturbate.
* Firstly you need to indulge in prolonged foreplay so that you can gradually build upon the excitement and arousal. Proper psychological involvement in important in such a case. You also need to learn to go at a steady pace and go slow whenever you feel that you are nearing climax. With gradual practice you would be able to perform much better.
* Your stress may be playing a negative role. You need to relax.
* Let me tell you that you need to be rational and have realistic expectations from your partner. I assume that your partner is not a 'professional' and so you should not expect the same output from her as you see in the items that you use for self stimulation and masturbation. Psychological invovlement is very important. You also need to learn to go at a steady pace and go steady whenever you feel that you are nearing climax. With gradual practice you would be able to perform much better and I am certain ejaculation would not be a problem.

Let me know if I could help further.
