Can you rupture your bladder from having sex?

Unlike. Unless something quite unusual in that episode.
Yes. It's very unlikely to rupture either a male's or female's bladder during penile to vaginal intercourse. Case reports abound of urethral and bladder injury from people inserting objects as diverse as paper clips, beads, pens, steel rods (just to name the ones I've personally removed). There is also a report of a woman rupturing her bladder using a hot tub jet for personal gratification.
