Why is it rude to do some positions first before others?
"During your first sex, the important thing is variation in positions. By smoothly changing positions, you can increase the variation in sex. The important thing is to match rhythm with your partner! Suddenly going to the rear entry position with an inexperienced woman is foolish. On the other hand, using the missionary position with an experienced woman is what a simpleton would do. However, the missionary position is very important. Take note that there are many variations to the missionary position. Sex must begin and end with the missionary position."
