Question: I am 24 and my erect penis is 2.7 inches, i have worried about this for most of my adult life. is there anything i can do about it?

Micropenis is a lot more common than you would think. Although most men do not talk about it out of sheer embarassment. One thing you need to remember is that an average penis size in the USA is 5.8 inches. That being said - that is an average. Many men are on both the low and high end of the spectrum. From lower than 1 inch to 10 inches. So while you may be on the lower end, it's not as big of a concern as you may have been treating it as.

If you are bothered by it however, there are options. Jelqing (manual hand exercises) are a great way to break in and increase both size and blood flow. If you are more dedicated to the idea of increasing size, a recent medical case study showed that use of a penis traction device such as Fastsize, can increase the length and girth of the penis by around 1.5-2 inches over 6 months. This would give you a great base to work with from there.
