masterbating after IUI

Breanna • 23 year old mommy to Jace(08•20•13)+Matthias(10•23•18) wife(06•03•16) baby #2 made through IUI and donor sperm.

it never came up between my fertility specialist and I but I was wondering if it's OK? I know that's how regular babies are made, sex and possible orgasms. but for some reason I just can't get it out of my mind that it's something I shouldn't do.
