A girl should have the right to her own beliefs, views, opinions, and choices. She should have the ability to freely express herself, and be respected and treated as a person and an equal. Girls aren't sexual objects. Being groped, brushed against, and called names are forms of harassment and abuse. The next time you see someone bothering a girl, speak out against discrimination, harassment, and abuse.
Some boys expect that a girl wants intercourse as much as they do.
They might also think that intercourse is as pleasing to her as it is to them. Girls have their own unique needs and desires. Unless you ask her, you may never discover what she might want or like. Open honest communication can help you build a better relationship, and you might discover lots of new ways to enjoy each other's company. Some people are only interested in sex, and don't care about another's feelings.
