Uncomfortable sensation in penis after not cumming/edging for a few days

Hey guys, if I don't come for several days, and during those days of not cumming I get hard (usually just by chatting online which gets me hard and often leaking precum), a few hours later I will have this really uncomfortable sensation like I have to pee. Even after I pee, it still feels like I have to pee and it continues for several hours. (Where I pee just a tiny bit to get a little relief.) Does anyone else get this, and if so, is there a way around it OTHER than ejaculating? I like to hold onto my load for a few days before meeting with a guy so its bigger. Thanks in advance for any useful info on this!
