A strange thing happened to me this evening. I spent about 3 hours masturbating on webcam, not something I do regularly, but it is very addictive. Anyway, after 3 hours I shot a nice big load, and felt a good intense orgasm. I then noticed that one of my testicles had swollen up by about 50% and felt very tender. When I touched it it was actually sore, I was worried I'd injured it. Luckily after about half an hour of resting, it returned to its normal size and the pain had gone. I'm just wondering if this has happened to anyone else. Should I take more care when masturbating, or am I going to die of some horrible testicle-related illness (I admit it's unlikely). Anyway posting on here is a lot easier than telling a doctor that I indulge in 3 hour wankathons.
