This might be due to two reason either your penis size is bigger or your wife vagina entrance is small enough. There are many women whose vagina entrance or opening is less in size which makes it difficult for the men to penetrate. In such situation make use of the lubricant for smooth penetration and smoothness at the time of intercourse with your wife.
