It works because there is a taboo force around sex, senses and pleasure.
Everyone wants to be freed from these limits. Only few people know how to do this and remove the barriers around sex and pleasure.
Sexual communication means that you open doors in a girl and attract her in that territory.
There is the thrill of the forbidden. There is the excitement of the pleasure memories.
The senses wake up.
This is a fight because most of what surrounds her daily has nothing to do with that. In fact, work, practicalities etc, take her away from these pleasures and excitement.
You, as a guy want to bring her to feel like a woman again. Free her senses and wake up her pleasure.
