Is this considered cheating?

Okay awhile back i was hanging out with my 11 year old cousin, note I'm 23, in alot of ways were are very close. So she didnt have a phone that was hooked up so asked me to get kik messenger so I did. And she had no clue that people used kik as a dating site. So you can randomly spin and itll let you talk to someone random and for what ever reason I tried it🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️ and started talking to this guy, he ask for a picture and I just sent him the one of me in well covered night gown, the pic was just waist up. And with a few messages later he started getting inappropriate, I had told him at the beginning of the conversation I was married, so I automatically blocked him and deleted the app. Would this be considered cheating? My husband doesn't mind if I wear bikinis and stuff to the beach but if sent someone a pic of pjs I think he would be very unhappy about it. So my question is, is it cheating?

What I was wear in the pic.
