Longtime Lurker, first-time poster.

My boyfriend and I have been dating for two years, he is 31 and I am 24. I thought we were happy together, until I came over to his house and saw he had at least a dozen GoneWild tabs open on his computer, where he knew I would see them.

I admit that I was crushed, and now feel very poorly about myself and like I am not enough for him. I lost my virginity to him after we had been dating for four months. He has always been sweet and caring towards me, so I was heartbroken to see that he was spending his free time looking at nude photos of other women, especially when we were going to see each other.

We had just had sex the night before, and he always finishes. I have never turned down his advances and we have sex at least three times a week even though we have separate homes. I am open and willing to be sexually adventurous (within reason of course) and he has never previously expressed disinterest in me.

My question is whether I am justified in being upset by this, or is this just something that all men do? Is his use of GoneWild a sign that he is unsatisfied with me, or that I can never satisfy him?

I love him and feel deeply invested in our relationship, especially after losing my virginity to him. However, I can't help but wonder if this is a sign of worse things to come? Did I make a mistake in sleeping with a man before marriage?

For background, I would consider myself to be moderately attractive. I am tall and slim, always make an effort with my appearance, and I was even a catalog model in high school. I cook for him whenever we spend time together, and even drop off home-cooked meals when I know he will be busy. I try and support him emotionally, and try not to be too assertive and masculine in my behaviors or demeanor at all times.

Thank you for any and all advice.
