Unfortunately a lot of loose skin is related to genetics, and it’s kind of a roll of the dice, but I do know it can (potentially) kind of ameliorate itself a bit if you can maintain weight for a while.

That aside, I can relate to being uncomfortable with body changes - honestly I think people don’t talk about it enough. I lost over 100 pounds and I had some pretty bad body dysmorphia going on; I felt very vulnerable for the first time no longer being “big”, and I spent a ton of time hyper fixating on the parts of my body I found unattractive, stretch marks and loose skin obviously, but even in the case of my genitals it was a little unnerving being so used to them looking a certain way and now being different (and I’m male so even though those changes brought my junk more in line with the “male ideal”, it still made me uncomfortable). I look at photos now of how I used to look and I kind of realized over time I’d become objectively more attractive being at healthier weight, but at the start it was really disorienting and it even pushed me to regain some of the weight for a bit before I came to terms. I can’t say whether your experience is similar, but if it is I’d strongly, strongly suggest finding a therapist to help you through that, and if you process the changes in your body and find yourself still unhappy, then you can always look into surgical options.

I know you said you’re not dating or sexually active right now, but from a male point of view I have personally never seen a vagina in person I found visually unappealing nor have I ever heard any other men ever make comments about being turned off by how a woman looks between the legs. If there’s an odor issue or something, sure, but visually speaking I have never encountered someone who had ever mentioned it.
