Is it cheating to send nude photos to other men?

I love my boyfriend very much but he is in another city for work. I'm bored of my loneliness and I'm meeting with someone on social media and I'm shooting nude photos. This is therapy for me. But I never cheat on my boyfriend. Because I love it so much. Here is a simple nude photo.

Every girl has the body I have, what's so special about my body. It's just a simple picture. I didn't cheat on my husband when a man didn't touch me.
