Glycerin-based lubes work well and are cheaper than silicone-based lubes. One brand of glycerin lube is "Wet". It even comes in flavors, like Kiwi-Strawberry. And a little goes a long way. Oh yeah, check Ebay for cheaper prices, if you have a credit card and Paypal account, that is. It's a good source for inexpensive condoms also.
The woman can also lie on her back with her feet in the air. This rotates her pelvis and opens things up a bit. Try it. One of my girlfriends had this problem and putting her feet up helped. You can bend the knees, just put those legs up in the air. No, I'm not kidding. I'm not sure if putting her ankles behind her ears is necessary, but you might try it. After penetration, you might try putting your legs down. See what works.
