Brief Answer:
masturbation does not cause sexual dysfunction.

Detailed Answer:
Hello
Welcome to HCM.
I can understand your concerns.

Please accept my best wishes for your marriage.

I have following suggestions for you:
1. First, do not worry. You would definitely be able to achieve erection on your first night. This anxiety of performing well on first night is common problem.
Size of penis and passing sperm in urine will not affect your capacity of erection.

2. Masturbation does not cause any sexual dysfunction. So its not contributing in any way to your problem. Do not worry about it.

3. Every man fails 1 out 5 times during intercourse. This is completely normal. If this happens to you, do not worry.

4. Whenever you go for sex, spare enough time in foreplay. You should not think actively about erection, your mind must be occupied with sexual/romantic feelings.

5. During foreplay your partner should try to arouse you and note that your penis gets erection or not. When she feels that penis is sufficiently erect she herself should try to put erect penis in vagina gradually and you should continue your foreplay feelings without being conscious about erection. You must try to enjoy and only enjoy. Once penis is able to enter in vagina and strokes starts it is easy to complete successful sex.

6. If your partner is not aware about this situation you can do on your own. You just should try to do sex without being conscious about erection. Enjoy without thinking of your ability to maintain erection.

7. If you face problem after above measures, another option is drug like sildenafil or tadalafil (prescription drugs). You can take it before 2 hours of sex for good erection. After 3-4 successful attempts you will have confidence and you can do without help of medicines later on.

Hope you find my suggestions helpful.

Feel free to ask further.

Kindly close the discussion if you are satisfied with the response and give your valuable feedback.

Thanks.

Brief Answer:
masturbation does not affect size.

Detailed Answer:
The average length of erect penis is 5 inches. But this is an average length. The size may vary from person to person.

The size usually does not affect sexual life. The partner's satisfaction is more important.

Also, masturbation does not affect penile size.

And there are no natural ways to increase penile size.
So, I would suggest you to not worry about the size. Just focus on enjoyment which the intercourse brings. And you will do well.

Hope this helps.
Thanks.
