I am 23 yrs old man,my penis size is 3.5 inch(when erected),how to increase my penis size & i can be any woman pregnant in this penis size yes or no ?

It is ok...: It is not the penis size that determines if you can get someone pregnant. If you are producing good sperm then you should be able to have offspring. In various studies they have found out that penis size does not correlate with sexual pleasure either. Who you are as a man in the capacity of procreating and pleasing your partner is more than the size of your penis.

Here are some ...: Many factors together to decide if pregnancy may take place, including the sexual functionality of both parties and the timing of their love consummation. Penile size is not the sole factor, but your size would not stop you to father a child as long as the aforementioned conditions are met. So, don't worry, just do it, and see. Best wishes ...
