I have been sexually inactive for quite sometime. Just recently I met someone and became sexually aroused and experienced dizzy spells for a brief time. A few days later, I engaged in sexual activity and a short time later experienced dizzy spells for a few hours. After these dizzy spells I still feel somewhat groggy and it takes some time to feel at myself. Can these dizzy episodes be caused from sexual arousal and activity? What can I do to prevent them or the intensity of the episodes?
