Why do girls have sex

I read the chapter why do girls have sex?in the book titled virgin sex for girls. My favorite story is in love by kayla she a 17 year old girl that was a virginity that fall in love with a boy name tom. They both work at a park. This is my favorite story  because tom an kayla got to know each other before they started a relationship. Tom didn't pressure her about having sex, and he respect her. He made sure that having sex an losing her virginity with him is what she really wanted. They became more close to each other after they had sexual intercourse with each other. the sad part about the story is when they had to break up because they go to different schools an hang around with different people but at the end of it all she didn't have no regrets about it because he was a good person
