as your penis is small,you have not to worry and pl do not feel inferiority complex
,size of penis does not come in way for getting children in future,
even after erection size is less than 3 inches,you may go for intercourse easily.
do not frustrate,do not think what your wife will feel.
please do not visit pseudo sexologist
as they will still depress you more and will tell about more length of size,all are humbug ,
