Welcome to Chat Doctor, Masturbation is a normal phenomenon in men and there is nothing wrong about it. As you masturbate thrice a week it is absolutely normal. Your penis size is normal, and you can have kids whenever you plan in the future.  Masturbation will not affect your sex life but remember excess of anything is bad and excessive masturbation may make you tired.  You are perfectly fine and have nothing to worry about. Hope that answers your question.  Chat Doctor. (if the answer has helped you, kindly indicate this)
