I HAVE read the thread, just as @CrazyMidget has.
Let's go through the PPs focusing on OP's "sexual hangups" and "lack of self-esteem", which by the way, she has neither - she wants sex more often than him and while she's a bit self-conscious because she's put on weight, she otherwise has no problem with being naked with him and him seeing her vulva WITH PERMISSION and WHEN SHE FEELS LIKE IT.
Growlybear83 had a lot to say, starting with, "how can you be embarrassed by the man who you are in a close enough relationship to be planning to buy a house with seeing your body naked? Has he never seen you without clothes on before or seen your ‘bottom half’?"
It was amazing (and worrisome) to see how many people - instead of focusing on the frightening coercion and manhandling perpetrated by the rapey boundary-violating partner - decided to hammer on OP's presumed prudishness. She came here to ask whether she was unreasonable to not like her partner sexually assaulting her (having graphically detailed the assaulting behaviour) and .... the answer from many was to blame HER for being "prudish".
There were so many like Growlybear:

I'm confused as to why you'd be embarrassed about your long term partner seeing your bottom half?

That kind of physical playing is not for me, but I know some couples like it. I do think you are a bit odd being worried about him seeing you naked though. You are not on the same page about these things and you both seem a bit childish to be honest.

Until you sort out your issues with sex and also your body you shouldn’t be in a relationship. This isn’t the right relationship for you but you also shouldn’t be In one at the moment anyway. This guy has seen you and your vagina probably like a thousand times he knows what it looks like.

I don’t see anything wrong with the first bit.. him trying to have a playful cuddle etc. I’m a prude but think you’re even more of a prude for not wanting your long term partner to see you naked or to physically desire you.
JoJuniorShabadoo
He saw you naked? And that's a problem?
PunnyPlumPanda
Absolutely wouldn’t bother me
my husband been down there loads and seen it tons. Plus it’s a beautiful part of our bodies. I’m proud of mine." [Whoopee for you, PPP]

I’m a bit confused about this - why would you panic about your towel coming off in the presence of your long term DP? Do you not get undressed in front of each other? Your initial situation just sounds like a normal playful interaction between a couple. Why are you panicking?" [If this is normal for this PP, maybe she should do the Freedom Programme, because she has normalised sexual assault]
YourWildAmberSloth
It sounds strange from both sides tbh. His behaviour is abusive and creepy. However it also seems strange that you're in a long term relationship yet you didn't want hime to see you naked (you said something about the towel slipping too much). Either way this is not a healthy relationship - you really need to walk away and ideally do some work on yourself through counselling/therapy.
Then there was the other bunch of PPs, who ALSO overlooked - or did not notice?/care about? - the sexual assaults and sexual harassment, and decided that it's simply a matter of incompatibility, that this is normal behaviour from a man. These people do not seem to realise that if you do ANYTHING sexual to someone, or even anything physical, you need CONSENT from that person. The fact that they think this is normal is alarming:
OwlCalledSage
What a waffle. You’re clearly not compatible.
AmITotallyBonkers
I feel like this is possibly not the relationship for you. I’d not bat an eyelid at this and enjoy the playfulness. Maybe you’re a mismatch.
ScrollingLeaves
You also do not seem at all compatible anyway.
Rwalker
your not compatible. a lot of people are touchy feely and very direct about sex
good for them. but unless your both in the same page it’s not going to work
Twinkylightsg
It sounds like you two just aren't compatible.
Dhangoinchains
Reading all your posts I think you just sound incompatible. He wants dominating and dirty sex and you don’t want him to see your vagina. It’s not a match made in heaven. I don’t think he sounds abusive though tbf, you both sound childish though.
Mumto2at
Your just not sexually compatible so it needs to end
Then there were posters with their own particular strain of victim-blaming:
Bonkers1966
Unless you are in the middle of a psychotic break or something, you have very poor taste in men and exceptionally low standards.
Brightlittlecanary
I think though when you’re living with a sex pest and pervert who will abuse your boundaries, it’s important to have your knickers on in future
Blomama
You both need to grow up.
And several even demonstrated sympathy for the predatory partner:
ByRedBee
He should dump you. it’s very weird it’s a long term relationship and you are so prudish about the lighting in sex
Truffleruffle
Dump him your obviously not confident in this relationship and he sounds into things your not. Sorry you’re not recognising that he has lots of emotional issues going on. You need to leave this relationship and go solo for a while to work out what you want I ca relationship.
And then there's you, @Sunshine231 :
You need therapy to work on your body image issues. It’s not normal to hate your body so much you don’t want your partner to see you naked. Not defending his actions as I don’t think he’s been great but for your own sake you should want to improve your relationship with your body. What a sad way to live your life. I have low self esteem but even I wouldn’t get upset over a partner accidentally seeing me naked.
If someone’s self esteem is that low I highly doubt they will have the confidence to leave an abusive relationship. Self esteem IS a huge part of driving someone to be able to leave when they are being abused. If you hate yourself to the extent you are far more likely to believe you deserve to be treat badly. Even if she has the courage to leave this guy, without addressing her own issues she will likely just get into another relationship with someone else who is abusive. Women with low self esteem are a sitting target for abusers.
While I DO understand your overall point, OP does NOT have body confidence issues:
"I don’t hate my body! I don’t feel great about my weight as I said but I don’t think I have this huge issue about how I view my own body, as it’s been pointed out the scenario we’re talking about is not just ‘seeing my vagina’ in the light of day it’s staring at it a few centimetres away in the position I was in and struggling we weren’t gearing up to have sex whatsoever either. Described quite accurately by a pp as an ‘amateur gynaecologist inspection’!"
So your advice is irrelevant here, and in the context of the thread, inappropriate.
Also, "Not defending his actions as I don’t think he’s been great" is a VERY tepid way to describe what this man did and is doing.
You - and SO MANY PPs - are weirdly focusing on the wrong things. What you have all seemed to have overlooked is that this man has sexually assaulted OP, and that his behaviour and the language in his texts are showing clearly that she is in danger of being raped by him.
