If this petty thing is your problem then you are not the right guy for her. Life lesson and take this to heart... Women are always right even when they're not. Saves so much wasted time and energy fighting over useless shit like that.
I am 18 M , idk why but I want to cheat on my gf , she is soo sweet but she doesn't agree to give me nudes, I just want to do all that stuff with any other girl and show it to her so it would be a little fun , anyone up for help
