What natural supplements are good for penis growth?

Nothing you take will make your penis grow you just have to learn to use what you have to its best abilities.

When you say your penis is small how small are you talking about?

Most of the sensation gained during intercourse for a woman is received from the first 2 inches inside the vagina as that's where the most nerve endings are.

If your slightly over weight then that can make your penis seem smaller as some of its length will be buried in the fat pad over the pubic bone, when you measure your penis push the tape back into the fat pad over the pubic bone and your get a better idea of your length.

Hi, Thanks for your feedback, my penis is not more 3" longs. Am not worried much about the size but about the ejaculation time, i normally ejaculation in like 2 minutes and am totally weak to continue with sex. Am not overweight i weight about 56 Kgs only and with a small body.

Let's discuss along this line of ejaculation.

3 inches is below the average make size but if you learn how to adapt what you have will be plenty.
If your having ejaculation problems and not able to last long is it just during intercourse or when you masturbate as well it happens?
One of the best ways to gain more control over ejaculation is to practice the runs start technique where during masturbation or intercourse when you first get the feeling your going to ejaculate stop and wait for the feeling to pass then start again and keep doing this until you start to train your body into going longer, it's not something that will happen over night and will take some working at.

See how you get on.
