Husbands friends sending him crude things

Do you wives get upset if your husbands friends send him inappropriate things?? My husband and I have a good relationship, I’m currently pregnant with #2, but he’s in the army and we have recently moved so he has a “new” group of friends. Well, one particular guy in this group (only unmarried one) recently sent my husband a video of naked women riding dildo bouncy ball things... which kind of upset me! We don’t watch porn, or go to strip clubs or anything of the sort, so this isn’t a ‘normal’ thing in our life. How would you handle it?
