Those of you with an IUD (Marina) has your man ever came inside you n became pregnant

I'm just a little curious to see how it feels but I don't wanna be the one dumb ass who tried it n got knocked up which isn't bad I love my bf but I'm just about to start school To be an rn it's a tech school but my doctor said that its basically no chance of me getting pregnant with this thing in I just wanna know if anyone has tried it and how long you've had it in I've had mine in for about a year #couriousiykilledthecat #butsatisfactionbroughtitback
