Biologically, intercourse is for reproduction; it is essential to understand precisely what happens and be informed about sex, it makes it safer and more pleasant.
You may think that you know everything about how sex works, but it is surprising to see that many people – even adults with children – have a very vague idea about what happens during sex. Knowing exactly what happens and why, is the best way to avoid the negative results of sex, such as unwanted pregnancy or a sexual illness.
It is not right to seek advice on safe sexual practices if you do not understand why they are necessary. So, if you think you already know everything, use that information as a review. For those who are less safe, it is wise to remember that it is wise to take the time to find out.
As far as biology is concerned, the sexual act is the means by which we reproduce ourselves. But when it comes to relationships, it is a way of expressing love, providing a lasting bond in couples, as well as the joy of forming a family. When you are young, you are only beginning to explore your sexuality.
For the sexual act to be successful, both partners must be thoroughly excited, usually through the preliminary game hugs, caresses, and kisses. The stimulated senses and changes occur in the genital area. Sexual arousal occurs throughout the body, but since boys get a lot more excited than girls, they must wait until girls “reach” them, so that both can enjoy sex.
