In brief: Flex away

If it's massive, you're squeezing the blood out of it, and this will make it briefly sore.
You might also be putting a little bit more strain on the tendon and getting a bit of bleeding there where it joins bone. But what the heck -- showing off is fun and if you haven't ruptured a tendon lifting, you won't rupture it flexing.
