Please help.

So I'm going to be having sex with a guy I like within the next few days. I'm super self conscious about these stretch marks on the insides of my legs. I'm thinking about just cancelling the whole thing because of it. No matter how many body positivity posts I read, it just doesn't help. I'm trying to just love my body, but I'm so scared that he won't. I know they're going to fade eventually, but someone is going to see them this weekend and I'm freaking out, man. Does anyone else have super red marks right here? Does your significant other like them or hate them? Someone please say something to make me feel better.
