One night stand to lose virginity?

I (24F) have never had sex. I know why - I'm incredibly anxious, anti-social, never really had any serious friends, and of course I'm not really an attractive girl (I'm 5'2 and 200+lbs, so thats a pretty bad combo) to make up for those personality faults. I turned 24 a couple months ago and I'm at a point in life where it's getting weird to say that ive never had sex or had a relationship. I'm realistic enough to know that I'll probably never be in a real relationship or find anyone who genuinely likes me, so I'm considering just having a shitty one night stand to get it over with and never see the guy again, but I'm hesitant cause I really don't want to embarrass myself or regret it. Has anyone done this or have any advice about this?

Edit: I am not actually announcing to anyone that I'm a virgin - I just meant that I've had lots of conversations throughout college and later with colleagues where the topic inevitably strayed to them talking about their dating and sex life, and I've had multiple people ask me about my dating history (of which I have absolutely none). Only a few people have asked me directly about my sex life, to which I kind of just awkwardly changed the discussion and didn't answer them. Only one person in my life knows for sure that im a virgin and thts really only cause ive known her for 8 years but she, also, has her life together in ways I can't even imagine for myself.

2nd Edit: My weight was a combination of medication (I was hospitalized for self harm a while back and they prescribed it to me) and untreated PCOS (diagnosed like 2 months ago). I can't really afford Ozempic but I have been trying to lose weight with very minimal success.

3rd Edit: Please stop telling me to lose weight I am already trying and half of these responses are already about exactly that

Final Edit: This thread has mostly gone quiet but I thought I might as well give a small update just in case anyone finds this in the future. I was able to speak to a psychiatrist who put me on a different medication, and I've lost about twelve pounds so far. I don't expect to ever be thin (or lose 80 pounds, like a lot of people were telling me I absolutely needed to do in order to be loved) but I'm hoping that I can get to a level I'm less self conscious of and feel comfortable in. I also put myself out there and went on a date (I had the dating apps but never wanted to meet face to face). I was pretty positive the guy would take one look at me and turn around or just ghost me entirely, to the point that I actually set a 20 minute timer before I could leave our agreed meeting spot and go home. But he actually showed up and we ended up hanging out for over four hours before he walked me to the subway station and kissed me goodnight (after asking me of course). He's planned all our dates meticulously (always asking me if I have any preferences to anything), he listens to my stories, picks up the bill before I can even think to reach for my purse, and he's just consistently been sweet and gentleman-ly throughout. I really hope he sticks around but even if he doesn't I'll still be grateful to him for treating me like I'm worth everything for this past month. It still doesn't really feel real that 2 months ago I was so positive nothing would ever happen for me and now I've had my first kiss and a cute guy is honest to god courting me. I do think I'll wait on the having sex thing after all, not because of all the comments saying that my virginity is precious that's kind of gross, but because I think he might actually make it enjoyable for me instead of something to check off my list and I want to be confident and comfortable if/when it happens.

So yeah, I guess if someone stumbles across this in the future: as much as I hate to admit it, your life really can turn upside down in an instant. I didn't think I'd ever feel this way, but I do and I kind of love it.
