I have internal itching within the penis from the base of my penis head to my testicle internally, like it's in the tube, quite irritating to say the least, when I urinate it feels slightly burning but does not hurt, if I squeeze the penis slightly while passing urine then it hurts a little. No soreness or Rash, or white discharge, blisters or discharge. My gf has had thrush recently but the symptons don't make sense, also this has been going on for 3 weeks now. Please help
