(NOTE: I am not a Doctor, only providing info based on my own experience.)

Depending on her age, she may be going thru pre-menopause... (yes, I know that this is a shock - I started pre-menopause in my late 20's, and it can last up to 10-15 years - akkkkkkkkkk). During this time, she may have high estrogen levels and have a hard time getting lubricated. This is normal. That doesn't mean there is no desire.. and can often times mean that she is more sensitive because she isn't as wet. (So when she says it is better, believe her.. it was for me .

As far as having to use lube.... think of trying to put something dry, into a dry hole.... doesn't work too well.... and can be painful....

Just go with the flow.. if you both are pleased no reason to be self-concious..
