Peeing urge

I'm not sure why but every time I've tried to mastrubate I feel like I need to pee... I think I have a weak bladder coz I pee like six times an hour (that's a lot) so is it something to do with that?. Also its not like pleasurable just the urge to pee ... I just feel the min I feel something go in it like pressures on my bladder ready to burst
