It's often a little harder for men to pee, partly because of the prostate and partly because the pee has to be forced down a urethra about 16cm long rather than 3cm. Most guys though can pee whenever they're capable of expelling 100mls+ and whenever they're 300mls+ from being desperate to go; otherwise it could be a sign of constipation or (likely innocent) prostate issues.
