I know that this is TMI but I am genuinely slightly terrified.
I just masturbated, and immediately after I came I got the most blinding headache at the base of my head. Lasted about ten seconds and then disappeared.
This has never happened before. I am still lying here having not moved. I am by myself in my house.
I am in good health and feel OK now but that was scary. It really hurt! What the hell could it be and how do I make sure it never happens again?!
