First of all, I think you need to realize that a woman's body only produces 3-5 drops of lubrication during sex, and usually that's only in the beginning. No more. So no need to feel so worried or pressured when it comes to your wetness, just keep a bottle of lube by your bedside and let your bf know why. Women also self-lubricate sometimes the way men can get erections: very randomly, and outside sexual situations altogether.
So if we think to ourselves that if we're not lubricating enough, it's because we're not normal, or our partner isn't sexy enough, that's flawed thinking.
(I personally recommend Liquid Silk, O My, Pink, or the more common Astroglide. Do not go for numbing or warming lubricants.)

As others have said, don't be afraid to explore your own body and learn what makes you feel good. That way, you can show your partner just what you like and how you like it. Open up to him about your fantasies and let him know that there are some things you want to try and be sure not to judge him if he may not be ready to try some things yet.

On the orgasm issue, I'd like to point out to the user shipping that yes, you can grow old and still never have an orgasm. It's not unheard of. My own aunt is in her late 50s with 3 children and is only just recently discovering the joy of orgasms.

Sex during your period is also not a terrible thing. It can even help relieve some of the pain you may experience during your period.

Please, don't feel so terrible about all of these things. They are perfectly normal and are common occurrences in most people's sex lives. If you continue to have these problems, I think it would be wise to seek the help of a professional sex therapist who can more easily calm your fears and help you come to understand your body and reactions to sex.
