I am going to get married in next couple of months. My age is 31 and my would-be age is 22. About 9 year difference. Will this affect our sexual life and baby’s birth? My penis is also small in size, hence can I able to give full satisfaction to her after marriage. Also need some tips for how to start having sex with my would-be. Is it necessary to have sexual intercourse at the first night itself or later?

Age difference of 9 years has no effect on sexual life and baby’s birth.
Women’s sexual satisfaction has more to do with your emotional bond, caring attitude and love filled foreplay/after play then size of your penis. Do not get preoccupied with size.
I believe first night is for getting comfortable with each other and it’s night of romance. Sexual act is a by product of romantic first night and not the goal.
