Orgasms while pregnant 😬

Okay I'm doing this anonymously because I feel kinda messed up for typing this lol. Am I the only one who's baby stretches out into some weird downward dog yoga pose when I have an orgasm? Like when I tighten my stomach muscles up while having an orgasm I can feel my baby pushing his little booty out and it looks like an alien is erupting from my stomach. This happened with my previous pregnancy too. Please, someone tell me it's not just me. And why does this happen?

I'm 17 weeks.
