It's difficult to know a girl's true feelings... If you just say "I want to have sex!" you should be able to get together right away, but it's hard to say that to someone you've just met... ``If you come to my room, it's a sign that it's OK to have sex, right?'' Men and women agree, but if a girl asks me ``Do you want to have sex?'' I hesitate because I'm afraid they'll think I'm being lighthearted. Even though they repeat such tug-of-war conflicts, it is only at the beginning that they are innocent, and once they have sex, they burst out and enjoy sex to the fullest. The real amateur SEX was extremely erotic! !
