Just that…
“What’s your definition of amazing sex?”
Me and my wife were discussing this last night, after the post about intimacy, and we started discussing what actually defines amazing sex… so I put it to the wonderful people of the forum, because I bet it’s amazingly varied.
I’m not sure it can be defined as such, as it’s a personal thing based on a number of factors like your perception of enjoyment, connection, fulfilment, memories you hold onto it etc.
I’ve had a large number of sexual encounters with a large number of people, so I’ve had a pretty diverse list of sexual experiences.
Many have been what I’d consider amazing, but often due to wildly different reasons. Sometimes it’s been largely due to chemistry, others due to emotional connection, others because I’ve perceived it as particularly kinky, others because it’s something a little ‘off limits/taboo’, others because there were a number of us, others because it’s been genuinely filthy, and lots of in between.
If I have a shortlist of my most ‘amazing’ experiences then they would almost all be very different.
Interesting question.
For me - it’s some pressure-free sexy fun where both of us fulfil our current sexual needs…no matter how big or small they may be…
That can run the gauntlet from one direction to the other . One that always got top marks for me was where we both were extremely sensual with a lot of full body contact and caressing . Where we were almost like one .
The other is animalistic , kinky and physical , where we both worked into a sweaty cumulation of semi rough hard sex that covered several mass orgasms by both parties .
As a footnote , my wife has been inactive for about 20 years , so ANY SEX I would consider amazing .
I’m going with the old … you need a connection, and this doesn’t mean you’re super in love like the notebook movie. But in fact you just need to get each others vibe.
As long as you both know the rules and what your both into then I’m sure you will see fireworks and also just “let go”. Sex is meant to be fun and exciting, nothing beats just feeling comfortable, giggling and touching each other in a safe environment.
But if you want my personal thoughts on what I enjoy, it’s slow and sensual with lots of edging. Seeing my partner squirm as I build her up and then stop several times before I take her over the edge is incredible
I may be the only one but the best definition for us is when you are finished your both laying there and laughing your absolute bollox off!! (Together obviously not at each other 
)
When you’re both so mind blown and breathless after sex, that instead of saying anything you just high-five 
I think for me its probably a combination of all of the above but I’d probably echo @Gareth mostly.
I’ve had a fair amount of sex with a fair amount of people and I think the term ‘amazing’ could apply to many experiences for different reasons, so I wouldn’t be able to define it.
There were times that I’ve thought it was amazing but then looking back it wasn’t really because now I have further experiences to compare it to. But it was still amazing at that time.
A few examples would be:
● with my ex bf, I thought the sex was amazing because feelings were involved. Looking back he was incredibly selfish in a lot of areas of the relationship.
●There were 2 men that were particularly responsive to my slow oily wanks & I felt like the cock whisperer 
●The first time having sex & kissing after the break up. It was with a previous fwb and I was super comfortable with him, it was really good sex.
●Travelling to meet a fab friend, we spent a bit of time chatting and getting to know each other and then we both broke our own rules and we had such good craic as well. He is also who I had my bi mmf with.
●My most recent sexual partner topped them all. I’ve never been so in tune with another person. It was sensual, loving, kinky, nasty filthy sex.
All very different, but all amazing experiences.
For me , its when both parties are in a state of heightened sexual arousal and nothing else matrers other than having each other.
When you are both in tune with each other, their pleasure matters more than your own.
When you give yourself completely to your partner to do with what they will.
Like @JoCat, I’m with @Gareth on this one. So many reasons/factors why it might be considered amazing.
If I’m really digging to describe A1, best-ever sex … it’s equally about emotional connection as physical satisfaction. Hugely important for me is that I know the person I’m with really wants to be with me … and freedom of expression is also massive.
Give yourself fully to me, don’t hold back, and you’ll go in my ‘best-ever’ dossier. 
For me, most of our encounters are what I consider amazing, because we know how each other work, have a deep emotional connection and our kinks/what gets us off align well…but I think that the memorable ones that you still remember years after are what I would define as those truly amazing moments 
Amazing sex starts with being aligned with my partners. They need to understand my body and my mood at the moment, as not all days are the same. I’m unable to verbally express my needs, so it really comes down to intuition. Physically, the ideal result is that I get enough orgasms and I’m also able to empty out all my excess fluids. My pelvic muscles should ache, my orifices should feel slightly chafed, and I shouldn’t feel my clit getting hard or a need to ejaculate for 12-24 hours.
Amazing sex would be utter abandonment in the moment, body quivering, earth-shaking simultaneous orgasms for both (all) participants, resulting in jelly-legs and waking up from your sex-coma 15 or so hours later not knowing what year it is.
It depends on the sex. Loving, intimate and in the moment is amazing for us but so is acting out fantasies and trying new things.
Oh and the times that you can’t move afterwards and her legs are like jelly, you just lay there in a state of euphoria
Good question.
I agree with others that there’s lots of different things that could fit that description, but for me it’s really down to the intimacy now.
My wife and I basically stopped having sex after our kids were born and we got real busy.
We went to therapy and now we have the most amazing sex I’ve ever had.
I think it’s because there’s a lot of trust, vulnerability and deep connection.
On a more physical level, it’s because we have a stack of lingerie, toys and I’ve lived fantasies out.
Amazing is about taking some risks, trying new things and for me, the visual of my sexy wife allowing herself to indulge in pleasure together.
When nothing else matters and it’s just the two of you, and you can feel the sex energy like you are one body.
That’s the stuff I remember 
My husband says it’s a ‘hat trick’.
That’s initially oral sex, followed by prolonged PIV in various positions. Finally he takes me anally which is where he leaves his cum.
I guess amazing sex is something that leaves you feeling utter warm bliss and trembling afterwards to the point that you feel completely satisfied yet giddy for the next time
When that sexual tension is there and neither party really tells the other what they’re thinking but it just flows and you end up just doing the deed without having to plan it out. Especially if you get the whole start slowly, kissing, touching then by the end youre like a pair of wild rabbits before just falling in a heap into each others arms not even bothering to ‘clear up’
I agree with loads of the above, for me.
Being connected with myself, happy in my own skin, honest with myself about likes and dislikes
Communication with my partner, being comfortable to ask for what I want and dont want
Feeling safe and understood. Knowing that I will be respected and safe word always being a trigger to stop no matter what
Physical attraction and emotional connection
All of the above go for him too
