Is this considered cheating? Smh

Soo I'm not in a relationship. But me and this guy are talking and I can tell it's getting serious, the problem is we live 8 hours away from each other for the summer. I recently started talking to a guy a met. I don't like him but he turns me on and is so nice to look at. BuT he lives 4 hours away and occasionally we send each other nudes and naked videos and always talk about sex. I tried to get the guy I'm really into to do the same but he won't get into it, this doesn't make me like him any less, it just makes me so more for the other guy. Thoughts?
