The vaginal orgasm and clitoral orgasm are so named because of what is being stimulated at the time, not because each part has their own separate orgasm. The orgasm itself is just an orgasm. They may feel different for the woman, but they originate from same nerves and it's the same muscles and orgasns that contract. (Saying they're different is like saying a man has two types of orgasms too, one from oral, one from intercourse.)
As for the fluid, a very few number of woman actually ejaculate during orgasm, and if she does, it's through the urethra. This most often happens during vaginal penetration, but not exclusively. In general it seems a lot of women don't care if they ejaculate during sex, so unless your gf is dying to do it, I wouldn't worry about that being your goal. Most women are probably quite contents with their 'regular' orgasms.
As for question 2, since only 10-30% of women orgasm from vaginal penetration alone, I think your odds would be better focussing on the clitoral orgasm.
Now not to stomp on your sexual prowess, I have to comment on the questions from your first post. I hate to say it, but if your gf claims she is having up to 6 orgasm at each encounter with you, I would think she is totally exagerating. As to why she would do this, you would have to ask her, but she probably doesn't mean anything bad by it. I'm guessing immaturity. It is an unfortunate practice of some women to feel obligated to have 'easy' orgasms to show their partners how good they are. Asside from her not ejaculating, is there any reason to think she is not orgasming, or are you totally taking her word for it?
