First  Overview What Is Sex?

Sex means different things to different people. Above all, it is a healthy and natural activity. It is something most people enjoy and find meaningful even if they create meaning in different ways.

Whether you are straight, lesbian, gay, bisexual, queer or questioning, you have the right to decide what sex means to you.

Are you unsure about your sexual interests? Are you curious about what you might enjoy? Are you wondering if you are ready for sex? These kinds of questions are perfectly normal!

Sex is not just vaginal* intercourse. Sex is pretty much anything that feels sexual. How YOU choose to define sex might be a moving target during your teen years. Your sexual interests may change over time, and that’s okay too.

I find it hard to talk about sex.  Is there anything I can do to make it easier?

  • A simple place to start the chat is with yourself.
  • Take some time to privately explore all parts of your own body. While you are at it, think about what thoughts, fantasies and sensations feel good for you and how you might like to experience sexual pleasure with someone else.

Sex just doesn’t feel right for me.  Is that okay?

  • Yes, this is definitely ok. Only you can decide what feels right for you when it comes to sex.
  • You have the right to say no to sex. No one can or should force you to do something that doesn’t feel right.
  • If, for example, vaginal sex is not something you want to do, there are many other ways to explore your sexuality and enjoy a fun and loving relationship with someone else

What does “sexual activity?” mean?

  • Sexual activity is any activity that is considered sexual by the people who are involved. It can include the following activities and more:
  • vaginal sex
  • anal sex
  •  hugging
  •  kissing
  • any sexual touching
  • oral sex
  • exposing your body to another person
  • taking sexual pictures of another person
  • showing somebody pornographic images
  • and more!

Sex In Medicine

Sex differences in medicine include sex-specific diseases or conditions which occur only in people of one sex (for example, prostate cancer in males or uterine cancer in females); sex-related diseases, which are diseases that are more common to one sex (for example, systemic lupus erythematosus occurs predominantly in females);[1] and diseases which occur at similar rates in males and females but manifest differently according to sex (for example, peripheral artery disease).[2] Sex differences in medicine should not be confused with gender differences. The Institute of Medicine recognizes sex differences as biological at the chromosomal level, whereas gender differences are based on self-representation and other factors including biology, environment and experience.[3] Sex differences in medicine should also not be confused with sexually transmitted diseases, which are diseases that have a significant probability of transmission through sexual contact.

Historically, medical research has primarily been conducted using the male body as the basis for clinical studies. The findings of these studies have often been applied across the sexes and healthcare providers have traditionally assumed a uniform approach in treating both male and female patients. More recently, medical research has started to understand the importance of taking sex into account as evidence increases that the symptoms and responses to medical treatment may be very different between sexes.

MRI Scanner Takes a Look Inside Human Body During Sex

The video above compiles some of the most striking videos captured by an MRI machine, including a quasi-NSFW clip of a couple having sex. Magnetic Resonance Imaging has been commercially available since the 1980s, but more recent improvements in resolution and computing have made it possible to build videos from the scans, and even provide technicians with detailed real-time moving images.

MRI scanners generate an image of the human body by mapping the position of hydrogen protons, which are abundant in the water molecules and the fat in our tissues. The machines create a strong magnetic field so that when the patient is placed inside it, the hydrogen protons in their body align like a needle in compass.

By sending pulses of energy via a specific frequency of radio waves into the body, the MRI machine alters the behavior and orientation of the protons momentarily. When that radio signal is shut off, the hydrogen protons realign with the magnetic field and in doing so, emit radio waves that communicate their position in the body and the type of tissue in which the reside. Pretty brilliant, right?

What it’s like to make love in an MRI machine
In 1999 Dutch scientist Pek van Andel created the following video of a couple having sex inside an MRI machine, as part of a study on the feasibility of recording images of a couple having sex inside an MRI machine (hypothesis confirmed):

Ida Sabelis, an anthropologist and one of the subjects of the study, said this about her experience (through an amateur translator, apparently):

Suddenly I become conscious that I have a strange position: the only woman between four men, on the verge of becoming intimate with my lover in that machine, while the other three gentlemen in the next room are operating all sorts of machinery to take a shot of our inner side. […]

Then nothing for a little while. Confined by the space we make the best of it and that’s just not so uncosy. On a certain moment there’s sounding through the microphone “the erection is fully visible, including the root.” Again nothing for a little while. … The first shots are taken: “Now lay down very still and holding your breath during the shot.!” Forty rythmic little bangs of the magnets above us and then one may exhale. […]

It’s becoming pleasantly warm in the tube and we truly succeed in enjoying each other from time to time in a familiar way. When the microphone is telling us that we may come- insofar possible- and that only we have to inform them in connection to the photo, we burst out into a roar of laughter and some moments later we do what is the purpose.
