nervous about him seeing me naked for the first time

I’ve been talking to a guy for a few months who i’ve been friends with for about a year and i know he’s had feelings for me for a while. We’ve both agreed to wait until we were actually together to have sex but the sexual tension is definitely there, especially with this lockdown going on in our state. We’re planning to hang out soon but i’m so self conscious about my body. I’m 5’2 and 150 lbs and people have always told me “you don’t look 150 you look smaller” and i’m sure it’s because of my

clothing choice but there’s nothing for me

to hide under if we’re intimate. From what i’ve seen, i’m the biggest girl he’s talked to. Most girls he’s talked to have been super slim and average height.

I’m currently on a weight loss journey (only 4 lbs down since the start of may) but i’m just super insecure about my body i’m afraid to do anything with him even though I really want to. Any advice?
