Advice for a virgin please 😭😇

Hey girls, I need help so during this quarantine one of my ex- guy friends hit me up saying he wants to eat me out and then obviously things will go further of course. But he hasn’t talked to me in 3 years and now he comes out of no where saying all of this. So I’m still a virgin at 19 (which nothing is wrong with that) and I’ve been losing weight during this quarantine and I’m not going to lie I’m a pretty chunky girl I was 230lbs August 2019 now I’m 202lbs May 2020. My body plays a big role in this because I feel like I’m not good enough, no one will want the “Chucky girl” that’s also a virgin. And I’m not saying I’m not confident I very much am, and I’ve been so proud of myself for losing this weight and not gaining it back. But I think I’m embarrassed for him to see me with the way I look now. I’ve honestly thought of scenarios of putting my shirt on my stomach so he doesn’t see my stretch marks and my fat, or telling him to turn off the light. And I feel like I’m not mature enough for sex even though I am, but I’m just very conflicted with my emotions. And I have certain people telling me I’m late on losing my virginity and I need to lose it ASAP and honestly it’s messing with my mind. I don’t know what to do. And I’ve never done ANYTHING with a guy I feel like such a prude when I’m not. As you girls can tell I’m very unexperienced with boys and just sex and foreplay in general. I tease that’s what I do, but I can never go through with anything. I literally just tease and of course guys will get tired of that.

I need advice!!! Like how should I suck dick, confidence in bed, should I even give him my virginity.

This is my first time posting so if I can add things he has sent to me I will 😌 like a thread.

UPDATE: (BACKSTORY)

We’ve actually known each other since junior high 😂. (And him and I have history) And he was actually my partner during my quinces and then he stopped talking to me after because he was “utterly disgusted” with me because I talked to some shit (which never happened, I only talked good about that boy) and then him and I haven’t talked since we were 16, we’re both 19 now( so I’m guessing we’re more “mature” because of our age) But you can’t just come out of the blue and say “come over” and “I’m gonna way that pussy out for a late night snack” like it’s not right. I’m not that kind of girl, I never was, I never will be. My friends say the same thing and that I shouldn’t be worried because if he is hitting me up he knows what I look like so he is attracted to me 🤷🏻‍♀️ but idk maybe quarantine is making people crazy and just horny honestly.
