Hello, I am 37 years old and have a very healthy sex drive. My wife does not share my drive so occasionally I masturbate as well. Yesterday I nearly passed out while masturbating in the morning and became very faint and almost nauseous. After laying down for awhile, I was fine. Went out to lunch and shopping and started developing a headache, came home, took some aspirin, and after a nap was fine. My wife and I watched some TV and then started to have sex, after about 10 minutes, I developed a pain in the rear or my head and top of my neck and once again felt nauseous and had to stop.
I have NEVER had these issue before and so now a little worried. Any ideas? I plan to go to the Dr to talk further, especially if it happens again, but didn't know if these were symptoms that might necessitate me getting in quickly. A friend of our family recently was diagnosed with a brain tumor, so has me a little paranoid.
