No not cheating but it is walking the line. If your boyfriend was omnipotent and knew for a fact that it was just a game and you would never cheat on him it would be fine. But he isnt. He's a man who has doubts and worries. He's thinking if she will do this what else will she or has she done? It's trust. Once there is a crack it's hard to fix. Men are insecure creatures. I've never even slept with or dated a women for various reasons but the biggest reason is the soul shaking horrifying fear of betrayal. The more you love somthing the more afraid you are to lose it. Also in today's society both men and women a much more likely to cheat and much more likely to lie about it. Also women always seem to bottle up thier worries and desires. Never telling a man what she truly wants desires and thinks. They build white lie on top of white lie in an effort to save a man's feeling. All that does is create invisible distance between you. The man thinks everything is fine and he doesn't need to change or do anything better so he doesnt. The woman becomes more and more dissatisfied and eventual she will blame him for everything but if she had been 100 percent honest the guy would know what he needs to do. Also the guy you where chatting with was not a friendly guy he was leading up to more and more sex talk. You know it he knew it and your boyfriend knows it. Do you jack off? Seriously?
