<human>: Give me the gist of the text in a nutshell

We were laying in bed last night and I was going through old pictures on my phone looking for a throwback picture to send a friend on their birthday and haven't scrolled all the way to the top (oldest photos, going back 3 years) since I took most of them. 

I finally found it and we are semi-cuddling so he sees all the pictures there isn't anything I mind if he sees, except this one I forgot to delete a long time ago of a hookup who sent me a shirtless photo showing off his abs. I completely forgot about it and he says "What's that? Scroll up" and I click on it and I told him I'm embarrassed and promptly deleted it. 

I felt bad because my boyfriend is bigger guy, around 265LBS he's recently been working hard to lose weight and I could hate for him to think or compare himself to that stupid picture. He tried to make light of it saying "Why'd you save it?" and chuckled. He hasn't said anything but I'd rather not bring it up again either.
<bot>: boyfriend saw shirtless ripped past hookup picture on my phone, I deleted it but I'm worried he won't think he's good enough.
