Freaked out!! Found a sex tape of my husband and his ex girlfriend!

Seriously feel discusted that my husband even made a sex tape I was cleaning his closet and found it it was years ago it's on VHS i didn't know what it was and even joked it was a sex tape I couldn't believe my eyes I told my husband and he just laughed he thought it was hilarious and asked if his body looked good and how was his form.  I didn't think it was funny he said I was acting crazy but comeon how does he not know he had it still. Do you think I should be upset?
