Hi, so tell me if I'm wrong but I think I have a sperm allergy. When masturbating sperm got on the inside palm of my hand and created a burning sensation. My arm feels weak in general but more specifically my elbow/shoulder ache and my hand is tingling and feels a little numb. I feel like my triceps are also aching a little. This is kind of weird, I'm 19 and haven't had this happen to me before. This may seem irrational but I feel sperm could be linked to MS (multiple sclerosis) which my mum has. I assume the proteins in sperm are similar to that of us, which may explain why the immune system confuses things and then attacks itself. Of course, I'm speculating, but I'm just worried, to be honest.
