I sometimes spray when peeing. i find this a problem as it happens a lot. is there something to prevent this from happening? started since i was 7.

Urethral stricture?: Occasional spraying could mean a transient plug of mucus in the urethra; residual semen after ejaculation; or pre-ejaculate fluid after sexual arousal. But for a problem nearly 10 years, you should be checked for urethral stricture, i.e. partial blockage. Over time, this could become a fairly serious problem, but easily treated now. Discuss with your doctor, who might refer you to a urologist.
