[|Human|] Hi Doctors,Last week I noticed a slight pain in my left testicle- top part- a day after a sexual encounter where there was no oral sex only masturbation with another person.. I thought I caught an std and thought it would swell but it never did. The strange thing is the discomfort disappeared with more intake of water- know strange. The strange thing is my ejaculation have not been the same since. I have masturbated 3 times this week and noticed a significant change. I am a major shooter with lots of semen and now it is the complete opposite, more like a big squirt. I have no idea in the cause for this drastic change but my libido has decreased because of it. The sensation and excitement is not the same. I was wondering if perhaps the cause for this change was an std or a clogged vein.Thanks
[|AI|]  Hello, Testicular pain can have causes that aren't due to underlying disease. Examples include trauma, tight pants or underwear, jogging, cycling or decreased blood flow to the testicles from prolonged sexual arousal. Still, you should consult a doctor for physical investigation.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  V. Anand, Psychologist
