I'm currently in my first real relationship and I've been with my girlfriend for just over a month. Since I've been dating her, I've had two opportunities to cheat on her. I really like her and care about her a lot, but when both opportunities came up, I was incredibly tempted to hook up with the other girls. In the moment, I remember that I have a caring girlfriend and it would be wrong to hook up with someone else, but how can I prevent myself from even considering cheating?
