Hello, and I hope I can answer your question.
Female sexual arousal is part physical and part mental. It is absolutely not necessary to remove the clitoral hood in order to have clitoral sensation. You can (or your partner) can pull back the hood during stimulation, whether oral or manual. Using an external lubricant can make the genital area feel more sensation, especially around your
clitoris. Lubrication (both external and internal) increases sexual sensation- which is why your body naturally produces it during arousal and orgasm.
The best way to figure out how to best have a clitoral orgasm for you is to practice, either with a partner or alone. Alone enables you to figure out what techniques work for you without the pressure of having to please your partner. There are also products (available in stores or on the internet, depending on where you live) designed to increase sexual sensation, both topical products and vibrating devices. These can be used alone or with a partner to increase clitoral stimulation.
Regarding lubrication, it is normal for your
vaginal lubrication to increase and be at its peak at the time of orgasm, and some women ejaculate a watery substance at it's climax. This is a natural means that the body has to make it easiest for sperm to swim and survive in your reproductive tract. The system is designed to be "wet", because sperm die when they are exposed to air. Your body's sexual functioning is designed to help you reproduce, and being "wet" is part of that process. Normal healthy sex involves an exchange of body fluids and being comfortable with your body will enable you to enjoy sex as much as possible. So in summary- a "dry" orgasm really doesn't exist, and lubrication- both internally and externally, is a natural part of sex and will increase your sexual sensation and make it more pleasurable for you and your partner.
I hope this information was helpful and that I answered your questions.
