Hello
This is really a question for a gynecologist, since your lack of lubrication may be related to some physiological condition. Generally speaking, if you're turned on, you'll get wet, unless something else is going on. The suggest of having your partner give you oral sex is also a good one. This may help provide some lubrication that you lack.
But if you want answers, you should see your gynecologist for a thorough exam. Dr. J
I've dealt with that before. Things I've tried is watching ficks before sex. A lot of foreplay. Also when a guy performs oral sex on me before sex that has always worked. Try those things and see if it works. Also water and exercise does help believe it or not. ;) hope this helps.
