Hello sir i m 27 and my pennis so small
The size has no roles in sex.
Hello thanks for using ask a doctor service
Dear friend size of penis has no roles in sexual intercourse and pleasure. If you have good and strong erection then even if the size is small even then you will be able to please any girl.
If we go by anatomy then only outer 2-3 cm of vaginal wall has sensitivity so even a small penis can stimulate the vaginal walls.
The size depends upon genetics, race, nutrition etc and it can't be increased with any means so stop worrying for that. If your erection is normal then remain relaxed.
On an average size of around 3.2 inches in erected state is considered as normal.
Still have doubts please ask again.
