Hi I am 29 years old, recently married for about three months now. My wife is 27. We have very healthy& Happy marital life. My Small worry is, i am unable to penetrate fully into her as she complains of too much of pain when we try to do that. But we do indulge in lot of foreplay and lot other activities to keep us lot exited about sex. She is cooperative in words , and asks me to penetrate forcefully, but looking at her pain when i do that, i am afraid i might cause her lot of pain & damage due to this forceful act. Please suggest me how can we make this event less painful at the same more memorable event of over life
