I'm just curious if urinating makes a guy last longer because I know my SO and I went at it last night and we had a good 2 hr session which is longer than the normal 1hr 1/2 session we have.

We didn't do anything different as per say but I know for a fact I took a piss prior to last nights activities and it "seemed" to relax me a bit more? I dunno is it just me psychologically or is there a medical reason behind it? As I notice after I take a piss and clean myself, I can sustain a woody for quite some time as opposed to not takinga piss.
