I agree with everything she says. I feel like if my boyfriend going to lust after someone new everytime he sees an attractive woman than he might as well be chasing after all those other women.
Why be in a committed relationship with someone if you're not satisfied? If my boyfriend is picturing another woman when he's making love to me than I cannot believe that he is satisfied with me. If he's picturing what it would be like to have sex with an attractive woman he sees at the gym, I don't think he is satisfied with me.
I'm not saying it is wrong for him to recognize or appriciate attractiveness in women because it is impossible not to. I appriciate actractiveness in other men when I see it but I leave it at that. No it is not my natural response to start lusting after every attractive man that I see.
If I am happy in a relationship I don't need to. I don't care what other men would be like in bed and I don't need to look more than once. The only times I have lusted after other men while being in a relationship with someone have been when I didn't want the relationship anymore.
