Are British pants really effective? What effect do they have? Actually, it's no use. It doesn't matter what underwear you wear. It is not because the advertised products can have some good effects that they can no longer be developed. Moreover, drugs can't increase the efficacy of penis. The normal penile erection in China is 1 1 cm, and the shortest is 3 cm. If you have too low self-esteem, you can use penis lengthening surgery to improve it. According to the description you provided, I am happy to answer this question for you. In this case, in fact, he just said 18 in the advertisement, which doesn't really mean that it will be effective. I suggest that if you have this kind of situation, you'd better go to a regular hospital in time and hang a male department number for consultation and treatment.
