As you have no problem with porn is the issue that he said you were the only girl who could get him hot and that's apparently not the case, or that these girls he was looking at were 'skinny' girls? Or both? Your boyfriend is in a relationship with you, not some chick from the internet. People have differing opinions on porn and its place, if any, in a relationship and that's something only you really know if you're ok with.

You said you had some minor health problems with the weight so if this is the kickstart you needed to address that so be it. There's no need to beat yourself up over if it's the 'right' reason or a 'good' reason as it's not the only reason.

As for the porn girls being skinny, variety is the spice of life - how many girlfriends do you know who have a 'type' but crush on guys who are the total opposite? It doesn't mean he finds you any less attractive - particularly when the 'other' girls are from internet porn!.

I haven't read through the whole thread but here's the deal.

Men are visual creatures, they just are. My boyfriend doesn't even have the sound on his computer on when he watches it, which is so bizarre to me and I think to most women.

Here's the good news. Porn doesn't make him feel desired, porn doesn't answer back, porn doesn't make him feel wanted. It's just a time filler. It's purely a business transaction. THAT'S why you're way more attractive than those porn girls (most of whom are really not so cute, seriously). As girls we feel that if he's able to be aroused by those girls it means way more than it actually does. That's because we need more than the image of a naked man to be aroused. But that's all it takes for them, just boobs, ya know?

I'm rambling here, but anyway. Trust when I say I know how you feel cause I've been there. but really! there are so many more things you have to offer as a real women, that makes you infinitely more attractive than any porno girl, and weight is the smallest factor in all of this. I guarantee the thought has never even crossed his mind.
