Most of us think we know the answer to what a sexual activity is. But let's revisit it and see if you're surprised.

Penovaginal sex is what most people consider to be sexual activity. However, this understanding is a limited one.

Any action that arouses sexual desire may fall under the category of sexual activity. Any activity could include not only what arouses us physically, but also our emotions.

Sexual activities may or may not involve physical touch. And they may or may not involve a partner. Are you surprised by this definition of 'sexual activity'? If you think about it, you'll be likely to agree.
