Is it necessary to pull out while on birth control?

RyRy
My bf and I have been together 2 years, and I've been taking the pill (lo loestrin fe) religiously for those 2 years. We've always used the pill and pull out method. Lately I've been seeing some articles stating that there isn't much of an increased pregnancy risk whether the guy pulls out or not, so long as you are using your birth control pills correctly. I'm wondering how much truth there is behind this? Please let me know what you think/know please.
