What is cheating?

This is a bad indicator. There are definitely girls out there who would consider glancing at another girl "cheating."

Also a bad definition. Plenty of girls are disturbed and offended by their boyfriends masturbating. Plenty of guys do it anyway, and just make the effort to ensure that she doesn't find out. Is that cheating? No.

Is that crossing the line? I would say so. Is it cheating? Well, debatable. Cheating implies the physical act, but sending naked pictures to other people is definitely inappropriate in a committed relationship. It implies a willingness or a tendency to cheat, at any rate. You have every right to be upset about it.

Jam it back in, in the dark.
