Should I tell my boyfriend I used to be overweight?

Would you guys date a girl who lost a lot of weight?

My boyfriend and I are 22 years old. We’re both virgins and planning to lose our virginity to each other soon. He is very loving towards me and perfect in every way.

The thing is, I used to weigh much more and I never told him. I am terrified that when he sees my flabby skin from weight loss he will hate my body and want to turn away in disgust because he’s a virgin and his only exposure to women’s bodies has been from porn. He’s probably expecting me to have a really nice body.

Before, he said his criteria for dating a woman was that she’d be “not fat”. He’s also from a culture that doesn’t appreciate extra weight at all. Even though I’m not “fat” now it’s quite obvious that I lost some weight.

Should I confess to him before the act takes place? It feels like such a vulnerable thing to lay bare as i was bullied for years for it among other things. I don’t know what to do. Should I give him an out to leave if he doesn’t like my body so he doesn’t feel obligated to me?
