NN, my girlfriend of two years went on a study abroad in Denmark. Before she left i brought up the idea that she could have sex with one guy while she was out there (the idea of her still receiving sexual pleasure when I am unable to give it to her thrilled me) When she did this and told me(details and everything) it made me incredibly depressed. I didn't react in the aroused way i thought i would. I am frightened that I may begin to resent her. How could she want another man? Why did I do this?
Well you have absolutely no reason to resent her, so I’d stop worrying about that. You mention that you brought up the idea of her being with someone else, so she simply followed through with your suggestion. So the only person at fault here is you, I’d take this as a lesson learned. On paper all sorts of things can sound exciting and sexy but when put in practice they can end up being not very enjoyable after all. And it’s totally normal for anyone to have thoughts or desires for other people, and since you suggested and gave her permission she was totally in the right by hooking up with someone else. It’s not the end of the world, sex is sex, it’s not a big deal. If you both still want to be together that’s the most important part, and know you’ll appreciate her monogamy much more.
