To be upset and put off by this comment

I would definitely not have liked that - just weird for him to say it. And as others have said - am sure he would have been delighted if you had mentioned the incredible sex with your immediate ex.

Its just thoughtless and bad manners.

I get it, op. It's like you telling him of your last lover who was sooo huge, but you knew it wasn't a ltr.
See how he feels with that info.

That would really upset me.

I vote crass and negging. Of course he has plausible deniability. "But I was just being honest!"

It would immediately turn me right off!

I can understand your instinctive reaction - it feels unnecessary for him to share.

Just out of interest, how do you think he would react/feel if you’d said something about an ex being amazing in bed?

Exactly this, I would feel like I need to always be as good as the ex! Un necessary pressure, he sounds weird.

I agree with you, OP. No problem with a partner having a past but I wouldn't want to know about it or think my own performance would be carried forward and reviewed in future relationships.
Not sure I'd end it because of this (clearly most people seem fine about it) but worth a discussion.

I bet if you did start mentioning it he would go very quiet!

It would put me off him too. Surely it's a very basic thing to not discuss in the very early stages of a relationship.

I dont think he said anything wrong and maybe if you cant handle hearing about past relationships then dont ask about them! If he'd started going into graphic specifics then I would say you had a point however, IMO the comment is pretty tame.

Nah its a warning to her. "Make sure you're always as enthusiastic about sex as she was, because you're always competing with her in my imagination".

I wouldn’t like it. Yes it’s truthful, but it’s unnecessary and not a great way to boost your confidence. I’m also not convinced he ended it if the sex was incredible, chances are she ended it with that reasoning. I’d feel a bit ick by it all.

He didn’t describe it in detail, did he? It sounds like an offhand remark that I, personally, wouldn’t attach any significance to. I can’t tell you how to feel though.

I suspect that this may suggest a deeper incompatibility. Some people enjoy talking about past experience, others don’t. I find it fun and refreshing and reflects my view that sex can be wonderful and fun even with people that you don’t necessarily have a great long term connection with. My DH hates talking about previous relationships and doesn’t like it when I do. I’ve learned to live with it but it impacts how much fun I have and I feel like I’ve compromised my pleasure. Neither attitude is right or wrong but I suspect that longer term you might struggle if you and he have different views.

Most men would say the sex is good if they are having orgasms.
I've got a colourful past but there is no way I'd tell dh because it is none of his business and I'm not interested in knowing about his. We are both open to any subject but agree we don't need to know everything that went before.

That would give me the ick. All these posters saying it shows character and that he isn’t shallow… the bar is so low!
Not a deal breaker if he recognises it was thoughtless imo.

I don't think I'd like this. Me being me, I'd be a bit jealous and would start worrying that I couldn't compare.
I'm sorry, but I think making you a bit insecure (is it what they call negging these days?) was probably the intention here.
It's good to have honesty in a relationship, but surely not to this degree! And not at the expense of someone else's feelings.

Because they were having an open conversation. These two have different definitions of openness.
Now they both know where they stand....
It's hard to give an opinion because it's not something that would bother me.....
Maybe give it time.....

It wasn't good manners. I wouldn't say an ex was incredibly handsome unless I could make it clear that the current partner was of course much more so. I'm put off by bad manners so this would bother me.

I wouldn't have wanted to hear this but I wouldn't call it off just for that. I'd do what you did and hope he keeps the ex-chat to himself next time.

*Have you assumed he doesn’t find sex incredible with you plus he is compatible with you?

I might’ve felt better if he’d said that when I raised my discomfort with his comment. He didn’t though*

Hmmmm.....might he be trying (very very very clumsily) to raise the fact that sex could be improved - with you and him?

I agree with this. Loads of men would stay with women just for sex.

I’d be Incredible Off-ing him this afternoon then.

but the thought of having to have sex with him this afternoon is not appealing

You don't have to have sex with him this afternoon OP, if you don't want to. You can say no to whatever you want, even if you previously said yes to something. Maybe take some time to yourself and just sit with how you feel for now.

This is a valid point of view too. You've got to be on the same page though - seems like they weren't, hopefully now they are.

I think his comment was unnecessary and immature. It was bound to make you think, what are his criteria for great sex, how is he critiquing you and your performance…gives a powerful mental image of him with someone else…

I don’t blame you for feeling uncomfortable @Marjoram2
