I masturbated and when i reach to orgasm i don't ejaculate. i've been doing this for 2 months(not daily).now i feel pain&swelling in testis veins ?

Dry ejaculate: Dry ejaculation may be due to backwards or retrograde ejaculation (diabetes), low testosterone levels or ejaculatory duct obstruction (see: http://theturekclinic.Com/services/male-fertility/ejaculatory-duct-resection/) typically dry ejaculate is not harmful but can impair fertility. Checking the urine for sperm after ejaculation makes the call. Swollen veins in scrotum are likely to be varicocele.
