Is it normal to masturbate with my own urine?

Sure why not, it's natural and totally harmless :)

But what if you under 18 you wont be able to bye lube or get a girl i say you gota do what you gota do

My massage therapist forced me to sit in her antique clawfoot bathtub giving me a surprise variation of a golden shower. Knowing I needed an orgasm she pissed all over my crotch until my cock and balls were completely soaked. Standing there next to the tub she ordered me to start masturbating using her urine as she nastily watched and giggled. Taunting me until I came she was showing her female superiority over me showing me that she really didn't need to service me herself. Sitting in her golden fluids with come all over myself she left the room and told me to take a shower. Yes it did feel demeaning but my girlfriend was very dominant and actually I was quite turned on as well. She hated guys especially clients begging to have their cocks stroked. Once I got cleaned up we went into her massage room and I gave her a nice long relaxing massage.

It probably is, if you have a piss fetish like me.
However, I suspect this post is bull, because urine is definitely not a good lube. If yours is, you might want to get that checked out.

be careful with that.

normally it's sterile when it comes out but... that's only if you're completely healthy. and it doesn't remain sterile - it's a good breeding ground for bacteria

What about masturbating with your own cum or saliva? I'm sure it lubricates better than piss.

I thinking can make a good lube. Just enjoy it :)

thats bull. Pee is NOT a good lubricant.
Use some baby oil or hand cream, or get a girl with a nice wet pussy !!
