<human>: I have been with my boyfriend for about two years now, and we have a great relationship with an active sex life.  I love him, he loves me.  Recently, he has been under a LOT of stress and pressure at work which, combined with the usual winter laziness, has led to him putting on a bit of weight.  He is very self-conscious about it, and is constantly apologizing to me for "not being better for me" and for being "gross" and "huge", and it kills me.

Here's the interesting part - frankly, I'm into it.  I've always wondered what it would be like to be with a bigger guy, and as it turns out I'm just kind of into the softness I guess, go figure!  I of course tell him that I find him so sexy, and so attractive, and I show him by touching him all the time, but I'm pretty sure he feels like I am just saying that to make him feel better.  

The other caveat is that he does want to lose weight for his own health (its hurting his knees/breathing/etc) so for those reasons I want to support his weight loss.  I also was attracted to him when he was smaller, so it doesn't really put me off or anything if he wants to lose the weight.

So, how do I show him/make him believe that I really really do find him attractive the way he is, while also making sure that I am being helpful and supportive in his weight loss goals?

Could you distill the essence of the text into 1-3 sentences?
