Anal male stimulation leading to urination?

Men, I found myself with this situation for quite a while now... Actually several years! EVERY TIME I stimulatye my ass using a dildo my penis is kept flacid diring the whole time (and I never have erection problems) and when I come Instead of cum i feel a stronger sensation and squirt some pee out, Im not complaining whatsoever but I'll love to know how "normal" this is? I LOVE the feel and everything but I've search all over the internet and found No explanation whatsoever to the matter... What part of me is orgasming? Is the fluid really pee? Why is my pennis kept flacid all the time during this? If I start masturbating normally right after that I get hard in a snap and cum normally is this related? Man, I have so many questions??? I discovered this on me since I was oround 15 and now I'm 35 and still dont know much about it???... PLEASE SOME HELP?!...

I recently bought a prostate massager toy because I have heard so much about them. And ooooo boy!!!! what a feeling I ever experienced!! As soon as I put it in, the feeling sensation is incredible being that it is curved perfectally to automatically rub your g-spot. I am a straight man and never thought of anal play most of my life. But I recommend to every straight, gay, and bi guy to purchase a prostate massager. But I do have a couple questions. I start of slow rocking it back in forth and makes my body quiver as I start to drip from my penis. But as I pick up the pace and rock faster, it feels so much pressure (feels awesome) and all of a sudden, I squirt a stream of clear (is this urine or something else?) fluid? But I do have to admit, I lay there catching my breath. I repeat this one or two more times before I feel "finished". Another question I have, is it bad if you do this to much? What is to much? I maybe do it once or twice a week. Anyone have similar experiences?

It is a different type of orgasm, and is way more intense than normal stimulation of the penis.  Having experienced it, my take is that it is what a woman feels when she has one of those really big orgasms.   Once I learned how to relax and just go with the feeling, I found that I could orgasm over and over just from a toy, and it was cum coming out, not pee. 

I'm 20, and I have experienced this many times and I love it. I have an insatiable appetite for it. I use a bottle because it's bigger, and I put warm water in it (my hole dialates a lot easier). After playing with my ass for a while, I can feel the squirt coming. When it comes, I gush and I moan. At the same time I continue to plunge my hole with the bottle, forcing it against the contractions of my ass (not too forceful) and I continue to gush. For me, this can be a 20 second cycle of assgasming, and I have to break because of exhastion. But it's soooo good.  

I've had this happen 3x, but was using the Tantus A-bomb butt plug and a vibrator just barely...I mean barely, touching the tip of my penis.  I basically had "uncontrollable urination", but was a watery/sticky fluid.  It was like I couldn't even stop the flow while stimulating the tip and was immediate after some anal play and working up to the large plug.  I'm assuming because there was a great amount of pressure on my prostate.  Was able to have to heavy urinating type streems back to back all with the tough of the vibe.  My girlfriend and I now have our own magic wants.  She jealous that I could squirt and she was yet to have one herself.  LOL..
