Sex can be a very beautiful thing. It is the ultimate connection of two souls, the beginning of new life, one of the best ways to demonstrate your love for someone. But, let's be honest, it's not really always that. Sex is neither what is portrayed in hallmark movies or in violent and sadistic BDSM porn. A lot of the time it is just a way to feel good and make someone else feel good at the same time.
That's the goal, but sometimes we are not successful. Sometimes sex is just hella embarrassing. There is so much potential for awkwardness, think about all the fart-like sounds your body can make. The ideal situation is that you do it with someone who makes you comfortable, and you then can both laugh it when you accidentally kick him in the face.
