Weird sensation!

Hi! 1st pregnancy here.. almost 20 wks. So my friend sent me this adorable video of puppies nursing on their mama. When I saw it I had this uncontrollable, almost euphoric tingling feeling throughout my whole body. Almost like supersonic butterflies... It was so weird!!! No leaking or anything but just really odd feeling! I re-watched it later and it happened again! Is this normal, and has this happened to you? Maybe not with puppies but with seeing breastfeeding? It was so wacky!!
