I have already had sex 10 times with my newly married wife. Everytime after naked both of us and while trying to have sex, my errection of penis will be lost. To have again errection, I have to move it with my hand for some time. After errecting, I always do my best entering my penis in pussy and moved up and down. After sometime, my errection will be lost unexpectly.
I had also visited with doctor, but he told me that it's not a problem, it will be solved after some days automatically. and don't worry about it. just try to have satisfaction.
And also, always, i give satisfaction to my wife doing by fingers. and to get satisfaction to me, it takes very long time. Please give me suggest about this problem.
The doctor is probably correct as far as s/he explained the situation. What is more than likely the problem is what is termed "Performance Anxiety" in which we guys worry about performing and being great in bed and all the other thoughts that we think about. The result is that our erection goes away or simply does not happen spontaneously.
If you can masturbate and achieve an orgasm when alone then this is pretty much proof that there is nothing wrong and that you are worrying too much. The more you worry about how you will do and will you do OK and will she enjoy it and whatever else is going through your mind, the worse it gets. The fix is quite simple. Stop worrying. Enjoy what the two of you are doing, and if mistakes happen, laugh them off and keep trying. Nobody is perfect the first few times no matter how much experience she or he may have had prior to being with you.
The two of you have formed a loving partnership and this means that you should work together and teach each other. She knows that you are learning and that the two of you will have to perfect a routine or script for what to do. Give it time and if you are not perfect, mechanically, know that in her eyes you are perfect in other ways. In a word--relax and have fun.
