I need help

So I'm a vergin and there's this guy I've been dating for about six months now and he really wants me to give in. But I'm not exactly the smallest person. I'm a little on the bigger side in my thighs. And I'm not the lightest eather. I'm just afraid that once the clothes are off he won't like my body and won't want to be with me anymore. But I'm to scared to talk to him about it what do I do. 😖😖😖😖
