The Five Stages of Penis Development

The five stages of penis development you will experience with any penis development programme (or naturally during puberty) are:

1. Increase in erection strength and hardness
2. Improvement in the upward direction of erections
3. More staying power and ejaculation control
4. Circumference of penis will increase
5. Length of penis will increase

Note that length increase comes after all the other stages have happened therefore you will always experience an increase in length after an increase in girth (circumference).
