No. Don't do it, you're being an idiot and your dick will fall off.
An as a supporting point, a four inch penis can be pleasing. In fact, four inches puts your dicktip around her gspot more when you're fully in there, which can make gspot stimulation easier and better.
Don't be worried about the size of your penis, it really doesn't matter THAT much until you get into the extremes, like 2 inches or 8inches
You can always have anal sex
