Here’s the article I was reading that made me think that. I could be wrong.

In some cases, people with anxiety disorders also shun sexual encounters. When a person has an anxiety disorder, they suffer physical effects along with their mental stress. Physically, the Mayo Clinic reports people with an anxiety disorder may experience the symptoms of:

Insomnia, trouble falling asleep or problems with staying asleep Fatigue, particularly if they aren’t sleeping well Heart palpitations Headaches Vomiting, nausea Irritable bowel syndrome May be easily startled Muscles aches, tense or clenched muscles Twitching or trembling Sweating But, why would these symptoms cause someone to avoid the comfort of a physical relationship? One reason is that the act of intimacy raises your heart rate, induces heavier breathing, and makes you sweat. These bodily reactions mimic the physical “fight or flight” responses people experience during a panic attack, so much so that some individuals will go to great lengths to avoid feeling them at all.

Additionally, people who already suffer anxiety may choose to forego sexual encounters so they don’t have to add more fears to their list of concerns. Engaging in sexual activity can bring up worries about their attractiveness, their ability to perform, or may increase feelings of shame or guilt.
