Hi my age is 22, the size of my penis is just 4- 4.5 inches when erect. I've tried having sex 2-3 times bt the girl doesn't feel my penis inside her. Is it because it's too small? My stamina is also not soo good . how can I increase the size of my penis? I smoke 2-3 cigarette a week. My hands shivers after I have cigarette. Is it because I have less
calcium?? How to solve all these problems? When i masturbate I cum just in 40-50 seconds... How can I get a bigger size of my penis and last longer?? What to eat ? What to avoid? What exercise to do? Please help
