Does the size help prolong the relationship?

How long have you and your partner been together? Do you still have great sex? How's the size of his penis does it help giving you that great pleasure and help prolong tge relationship?
Me and my boyfriend have been together for two years now, and still we have great sex and I admit, his d*** is the biggest ive ever had. Maybe if it wasn't for that we wouldn't be together anymore. Hahaa!
