My husband is longer than my bf, and my bf has a slightly larger girth. The sex is different, and I enjoy both of them equally. Even when having sex with both of them in a 24hr period.
Vaginas are generally very elastic
As long as your sex life is good for both of you now, that shouldn't change. She may find things that he does better, but you will have things you do better too.
Of course, the difference in sex is a large part of why I have my bf, sexually anyway, There are things he does emotionally that just wouldn't work for John to do because of mine and John's relationship dynamic.
Let me put that more clearly... I dom John, F dom's me. Not in a very strict sense, but in general inadequate terms.
