What to Do When He's Too Big. Down There.

What can you do to reduce pain while having sex with a man who has a large penis? Lubrication is the solution here. Since the vagina can stretch to accommodate the passage of a baby, it can fit your man's penis — if you are properly lubricated. Using a water-based lubricant is always a good idea.

A lengthy period of foreplay can also help you get sufficiently wet, and you can also use additional lubricant. Tell your man to take it slow when first entering you to avoid any trauma to your vagina. If you still experience pain, talk to your gynecologist because you may benefit from vaginal dilation — a therapy that can help with painful sex.
