To not have sex for 8 years because I have small breasts

That's actually quite derogatory.

I'm sure larger chested ladies might find that offensive in the way many might take offence about derogatory flat-chested "thank God I haven't got that problem" type comments.

I was on the under-endowed side for many years and those sorts of comments can be upsetting.

Twiggy, Jane Birkin, Kate Moss, Zendaya, Tuppence Middleton, Emma Stone, Lily Collins, Cher ... All famously unattractive women? I don't think so.
OP. I mean it kindly when I say you need to find some way of boosting your confidence more generally, not just about looks.
I have always had a comparatively mediocre figure and a face like a bag of spanners, but I still used to do just fine in my single days. I like a man with brain and a down to earth sense of humour who keeps himself fit and doesn't take himself too seriously, I find that most of those men like the same things in a woman. When you think about it, sex is a ridiculous activity; doing it with someone fun just makes sense.

Bloke here. I’ve found all kind of breast sizes attractive in the past. What do you mean by someone being 100% into you? How will you ever tell?

I think it’s sad your body issues are leading you to miss out on a fun part of life

Thank goodness dh never minded my tiddly little 34 As.

TBH, although I’d have almost killed for a cleavage when I was teens/early 20s, I’m so glad now that I never had whoppers - I look at very well endowed older women now (I’m getting on a bit) and thank heaven I don’t have to cart a massive pair of watermelons about.

Seek therapy OP. And perhaps stop posting the same question hoping for validation or a different response.
I agree that sharing your cup size is only feeding into the narrative and exciting the pervs.

I don't like abs. Truly. It looks like an oil radiator from the 1930s.

OP is this you too? Kindly, seek therapy, you seem 100% convinced that your belief is a fact. It's isn't, it's a belief.

It's either someone with a fetish or a huge problem but they've definitely posted before.

I responded on this thread then realised as it went on that so much seemed so similar to a previous thread. It was the OP's comments about men liking huge boobs and no hips or waist that did it.

I have checked and it was a thread started on 4 April by a user called Thischic, in that one he/she was talking about wanting men to think she was a 10 out of 10 woman but she could never be because of her small breasts and she wanted implants. That thread had a thousand replies, and by the end, despite 92% of votes saying men didn't care about boob size, the OP was still insisting that was men's number one decider of attractiveness.

So no point in engaging because even with the chance they're genuine, the OP won't change their mind in the slightest. If she is genuine she absolutely needs therapy even if she has a breast augmentation.

I used to be self conscious when I was teens/twenties but now I’m the opposite. I love my body, small boobs and all.
I put on weight a while ago and while my breasts grew so did the rest of me. I was unhappy and again self conscious. I had gone from being confident about being topless on the beach to feeling self conscious. I didn’t know how to dress for my new shape.
I have lots weight and with it the breasts but I feel like me again.
I’ve always had a good sex life regardless of the size of my breasts.

Work on your confidence.

I've never had a partner with big boobs. And there's been a few.

You’re so close to getting the point.

What you’ve said is 100% true. THE SAME IS TRUE ABOUT MEN AND BIG BOOBS. Genuinely not ever man likes or cares about them.

OP have a look at the Netflix series Riviera, which depicts high society thrills. None of the women having loads of passionate sex have big, or even medium boobs and some (the most intensely desired) are positively flat chested.

Have you seen how men online talk about Kate Upton? She gets so much shit about her body. Even with he big boobs

But nobody is perfect and it is give and take. Someone with fantastic tits might have cellulite. Someone with a perfect juicy ass might have small tits. Someone's huge knockers might be saggy. Someone with mediocre tits might have fantastic personality. Men actually do care more about a woman than just boob's when they're dating. Sure, people notice if someone at the beach has good boob's, that doesn't mean they want to leave you for that person.

The kind of shallow men you are talking about do leave women because they get older.

For God's sake, small boobs is not a flaw!

You really need to apply some critical thinking here.

Yes it is unreasonable that your insecurities are stopping you enjoying sex.
But if you don't want it then don't. There are definitely men that will be attracted to you and love your body. You just need to be open to it.
Do you know what's made you so insecure?
The current beauty standard isn't focusing on breasts at the moment anyway. Not that that should matter but I'm wondering what's made you think only large boobs are seen as attractive?

I find it really sad that you’ve not allowed yourself to be intimate with a man for 8 years because of a body part. Those are some of your best years that you’ve spent worrying and being upset about something that most men couldn’t care less about.

I have small breasts (A cup) and I have had no end of attention from men over the last 30 years, much welcome and some unwelcome. I have had many relationships and no end of men asking me out, or flirting with me. I had one boy (both of us were 13 years old) telling me I was “flat chested bitch” but since then (I’m now 44) I’ve never had a single nasty thing said about my boobs. All my previous partners have been very complimentary about my boobs, and my current partner adores my breasts. I spent many years feeling a bit self conscious about my breast size after what that boy said, but whenever I have mentioned in the past to previous partners that I was thinking of getting a breast enlargement, every single one of them told me not to because my build wouldn’t suit big boobs/they didn’t like unnecessary surgery/my boobs are gorgeous the way they’re are. I currently have a man in his late 20s making a very strong play for me who is always telling me how gorgeous my figure is and how sexy I am, and a close male friend of mine was telling me I had a perfect figure and I was his dream woman (fyi I don’t have a perfect figure but he obviously sees me differently to how I see myself). In the past few weeks I’ve caught a few men sneaking glimpses at my very small cleavage. All it tells me is that men like boobs no matter what they look like.

It’s taken me a long time to make peace with how I view my figure but I realised over time that how I viewed myself and how others viewed me was very different, and once I understood that it’s given me a huge confidence boost which I think is further attractive to men.

If you’re so unhappy with your boobs that it’s going to hold you back from finding a lovely man then you should just get a boob job, but in all honestly I think you’d find something else to fixate on as being “wrong” with you. I think maybe some kind of therapy to help you gain acceptance of yourself would be a better investment tbh. And I think if you would be interested in a relationship with a man, then get yourself out there and meet some men. You might be surprised that your view of them is very different to the reality.

You're being nuts OP. Im 43 with an A cup and have never had a problem meeting men who liked my breasts.

This absolutely. And if we’re generalising, I’d say most men are delighted simply to be in bed with a naked and enthusiastic woman!
