I saw some blood while milking my prostate?

Stop. let your body recover. give yourself several days if not weeks before you engage your prostate again (i would suggest no ejaculation altogether.). If you have any pain or find that after 1-2 weeks of recovering that you still pass blood in your ejaculate, go see a GP. This is not normal and a sure sign that your body needs to heal. When i was younger i had this happen without any direct prostate stimulation, a week of rest and i was good to go.

Also check your urine for traces of blood (brown or dark red urine). If you find this is the case i would go see a GP as you may be vulnerable to infections.

wontquit,

I agree with @Wired, you should definitely cease prostate stimulation for the time being to allow your body to heal itself. It is obvious you've applied enough pressure during your massage to rupture some small cappilaries. Monitor your self for any signs of subsequent infection such as pain, fever, abdominal soreness, swelling, difficulty urinating, etc. If you develope any of those symptoms it would be wise to see your doctor for treatment.

Most likely this injury is nothing serious, as you didn't mention any pain in your post, but in the future be a little more gentle with your massage. I've frequently read with regard to prostate massage that one should apply no more pressure to the prostate than one would use as if rubbing your eyeball. Be gentle, be loving and be safe.
Good Vibes to You !

I agree- keep an eye on it, but if there's no ongoing pain or fever, odds are that it's similar to getting a little blood when you blow your nose. Little blood vessels can rupture, but it's likely to be a problem unless more than a little bit or it keeps happening.

Next time, go softer. The Njoy toys are great, but stainless steel might be a bit too firm for you.

If you're young and otherwise healthy and are experiencing no other symptoms, seeing a speck of blood should pose no particular concerns. Small flecks of blood in semen generally mean nothing and I would assume likewise that small amounts of blood in prostate secretions in an otherwise young healthy gland should mean nothing. Obviously if you're getting close to 50 years of age you should already have begun yearly male check-ups from a urologist or capable general medical doctor, such as getting your PSA and digital rectal examination.

Seeing blood in your urine is a little different and should be evaluated by a urologist or again a capable general medical doctor, especially if you're a smoker.
