I am 35 years old. I've suspected for many years that my urine flow declined slightly in strength. I say suspected because it's nothing drastic. Unless I hold urine in for awhile, then it's hard to go. But that's always been the case. I notice after having sex, the stream is far stronger. Like super strong. If this were an enlarged prostate, would that happen after urinating? Would sex make me urinate stronger? Or does this just sound like maybe muscles relax after ejaculating? Thanks.
