Strange ejaculation

[PS]

At a masturbation some seconds prior to an orgasm inside on a member something starts to flow dense (I suspect that juice of a prostate), then begins an orgasm and an ejaculation.

Earlier the semen flew only during an ejaculation. What is it can be?

[doctor Tirsi]

It can be a secret of urethral and periurethral glands which is developed or produced during sexual exaltation and the sexual certificate or act for simplification of passage of a semen on a urethra during an ejaculation.

the Initial report from doctor Tirsi
It can be a secret of urethral and periurethral glands which is developed or produced during sexual exaltation and the sexual certificate or act for simplification of passage of a semen on a urethra during an ejaculation.

Earlier never such effect was. Whether there can be such, what at me an excess of juice of a prostate?
