Just Let It Go

So firstly let me state that I am not into water sports. I watch some porn vids that indulge in it but never have experienced it first hand yet with a partner or by myself. But every time i insert my aneros toy in me i get the urge to piss. I always use the bathroom before every session an sometimes I pause the fun to get up to go to the bathroom. But I just have been wondering what it will feel like to just let it loose and let it spill out and land where ever it wanted to land. On a few occasions a few droplets have left my dick head but it was mixed with thick streams of pre cum so it was't that big of a mess. But lately I just want to see what the big deal is about. At my local sex shop they have those waterproof sheets for cheap.

So my question is have any of you just pissed on yourself or as your orgasming a stream just released from your body unannounced? I know this sounds weird but that also excites me about the act. I like pushing my own limits sexually. So is water sports worth the mess or should i just try it and see what it all has to offer. I really like you alls advice.
