Masturbutation: Stopping The Practice Just Before Discharge

Aoa,

i am 17 years old. my problem is that I am a habitual of masturbutation. but i used to masturbate in a special manner. i mean i used to stop doing it just before getting discharged. doing this prevents my semen to come out but instead of semen, two or three drops of thin transparent liquid comes out. I am sure its not the semen, as it is thick. I want to know if it is safe to continue like this, i mean wud it cause any sort of sexual problem after my marriage?

Looking forward for your reply,

Thank You.
