How to differentiate between sexual arousal and anticipatory anxiety?

Anticipatory anxiety: is not specifically sexual in nature. We can have this prior to just about anything we do, especially if we are being evaluated for it. Feeling like we will be judged for sexual "performance" can cause anticipatory anxiety. So, they can be independent of one another or happen together. Focus on the feelings of others and it can help relieve the anxiety. Peace and good health.

Could be similar: If you are aroused in anticipation of sex, it would be similar. If other thoughts or events brings on the arousal, you should get evaluated by your doctor who would need a detailed history.

Interchangable: Terms are interchangeable. Ready for action is ready for action. Enjoy!

Stress is stress: Our physiological response to stress/ anxiety and arousal is the same. Our bodies don't differentiate between the cause or even if something is good or bad. Our bodies just respond, but we can control our thoughts about something and thus alter or manage our reactions. Talk to a psychologist about CBT and mindfulness and you will be well on your way to identifying your feelings.

If the anticipatory: anxiety is about sex, then they are the same. Anticipatory anxiety can occur in a variety of other circumstances, like just before Christmas, just before asking someone out, etc. Sexual arousal is more specific to sex, and should be fun. If its debilitating, see a mental health pro.
