Sadly in life, horrendous things do happen. Women can become paralyzed in their pelvic region from road accidents, disease and so on. They can lose all sensation in their pelvic area. Yet many paralyzed women continue to be orgasmic. However, our culture tends to perceive people with such disabilities as non-sexual. Indeed, medical textbooks refer to these orgasms as "phantom orgasms." This is a phantom of medical folklore.
Be that as it may, it is critical to understand:
A woman can have an orgasm without penetration.
A woman can have an orgasm without a penis.
A man can have an orgasm without an erection.
A man can have an orgasm without a penis.
In fact, some women (and men) have orgasms merely by willing them. They do not require foreplay, nor thrusting, to raise sexual tension first. This is rare, but it can and does happen. Keep in mind that people are individuals, and have very different levels of sexual drive.
The human spirit is a wonderful phenomenon. It can withstand the most appalling vicissitudes and still respond with courage and resourcefulness. Women are said to be more stoical than men. They are able to endure more pain, both mental and physical.
Loss of sensation is a savage assault on female primacy. A woman's first response can be equally savage and destructive. If she responds with a seemingly quiet and depressive state, this is as damaging emotionally as a raging and bitter response. Keep in mind that the healing process can be speeded up by orgasm, if so desired. Use a vibrator, erotica, anything which works.
In a loving relationship, the partner can take control. Seduce her out of her angry or passive state. Shock her out of grief and pain by relighting her sexual fires. Turn her emotional energies away from her broken body and back to where happiness awaits.
Avoid over-concern with her feelings. She is a woman still, a real woman, and will find your particular brand of "medication" irresistible. Tell her that she is desirable. Continue to enchant her until she has an orgasm. Then tell her she is so desirable that she must be prepared for another love making session soon.
