Porn movies come with a label indicating the rating or "porn factor", which is derived from the content. Some of these are produced and directed by women, and hence have a "porn" factor. These are commonly available in a selection of adult video websites.
Most adult movies online are shot for some sexual climax where the hero (actor) cumulates naturally. However, most of the movies show a fake orgasm at the beginning which makes the audience think that the real action is going to happen soon. For example, Jack and Jill are about two teenage love birds who are about to enter their first sexual relationship, but they stop at the door of a motel room due to some misunderstanding and end up having a love-making session in a bedroom. Later, the two girls reunite and end up having sex in a hotel room.
Masturbation is a common occurrence in adult videos and films, as it is in real life. Thus, you should be sensitive to this fact while choosing the movie. Masturbation in the movies should be mild, but if it is not then you might get offended and this can spoil your sexual experience.
