Unsolicited private pic from random guy

Ok this am I received an unsolicited dick pic from a random person in my phone. Just from the thumbnail on my phone I could tell what it was. I handed my phone to my husband bc I was driving and asked him to handle that for me. He replied to the person. He has also been pissy & not talking with me all day like I did something wrong. I get being upset about the situation but it's not like I asked for it. He said I would be mad too if someone sent a pussy pic to his phone. What's your opinion on the matter?

** Update & more info**

I don't know the person who text the pic. I've had my number for 2 years. I assume that person text me by accident. It's not the first time I have received a msg not intended for me. I understand the initial shock & being upset about the situation. The last thing he said to me b4 being dropped off @ work was your luck I know you. && husband has since told me he knows he has nothing to be worried but he couldn't help but b pissed at the situation. & @ that person for doing something like that. My husband and I are really modest people. We don't even send each other pictures like that. Thanks for your opinions!
