Weird question but I need opinions!!

I had my first OBGYN appt. today and he did a pelvic exam and right after having his fingers inside me he sniffed his fingers before he took his gloves off. My fiancé was in the room and the doctor said it's ok I have to. He never explained why he did this and I'm just curious if anyone else has experienced this before!?
