I have fear of bad performance of sex. In 1 or 2 years I will get married. I have never been in any relationship in past. I get hard erections during masturbation but when it comes to meet a women, I don't feel confident. By suggestion of my gym trainer, I tested my testosterone, it was 858 ng, it was tested after 3 days of no masturbation. I am still worried about my sex life and penis size. I don't have experience so I am not Sure if I will give a good impression. Please suggest me how to increase testosterone, confidence and penis size. I am afraid of tablets, please suggest me something natural.
