Hi, I recently tried anal masturbation and I after felt the symptoms of the stomach flu (Nausea, diarea and a strange stomach feeling(not pain). I also noticed small amounts of blood when I stopped, I was very gentle aswell and I experienced no pain at all during any of it. I am getting paranoid thinking it may be serious because having a perferation has about the same symptoms but it says serious pain, which I do not have. I fear my mind may be making it worse, Because it all happened after I look on the internet and started to worry, I bearly had any sleep last night because I got so nausous I had to lie down in the bathroom. I also read that because of I am stressing about this I may be causing most of this myself, I do not have a fever, although I am a tiny bit hot (It is generally hot now so I think that is why) I also have a headache but I think that is because I havent had any water recently. Help I am scared, and just a tiny word that it is ok will help me a lot..
