When we get a round of applause from the other people on the bus - that's incredible

Having that extreme mental and emotional connection with someone that you deeply care about.

The fact that I am having sex is incredible.

If I can still remember it three days later, it was incredible sex.

Also, when my favorite agnostic/atheists (lady) screams...“oh god”

As long as we both finish and have good food nearby after ?

A partner usually helps.

Oh boy. I suppose its good sex if both people get some degree of pleasure out of it. Climax or no climax. I don't necessarily have to climax. If she is smiling or laughing i know she is getting some enjoyment which gives me pleasure. So really the pleasure comes from the close contact and the camadarie.

Me at least once, them at least twice and we're surprised by how late it is when we stop from exhaustion. Being able to look in their eyes during to say, and mean, "I love you" takes it to a next level.

To me the best sex is when all those involved experience emotional, physical and mental satisfaction. When the pleasure extends further than the genitals, further than the body and in to the pleasure centers of brain. Meaning the congress is memorable for more than the orgasm and is genuinely recalled with genuine affection years and even decades later.
I have been lucky enough to have had sex like that perhaps four times in my life, two of them were with my wife and two with other people, prior to my 2nd marriage, non of them involved my first wife.

For me, LOVE is vital, I have never had sex with a woman I didn't deeply love.
I like tons of fore play, maybe even days of it, then slow, relaxed undressing each other as our heart beats in sync. As the kissing and touching starts, we both forget about every other thing in life, all that exists is you wanting to please her more than yourself and her the same. As our sweat becomes united and drops as one, we too become one, with each other and the universe simultaneously.....and of course, multiple orgasm for both.

When you show her the four bite marks on your chest and she doesn't believe she did it.

If the woman actually enjoyed herself.

There I said it.

When a man actually LISTENS when I say what gives me pleasure, and RESPONDS appropriately.

This is rare.

Any.

Sex that doesn't include any actual sex lol

Sex that is not credible. When my wife asks if we can run upstairs and have sex... that's not credible. At our age we can only one or other... not both.

Incredible : "The was so good that the neighbour has cigarettes after that."

When's it's incredibly difficult to let go of each other ...

Depends on the definition of "incredible". Claims to have had group sex whilst free falling during a sky dive I would find utterly incredible, but credible if the participants were still in the plane. Lol

At my age? The bar is low

Sex? What's that?

The worst l ever had was wonderful! ?

There's only good sex - there is no bad.

Pheromones, hormones, experience, preferences, trust, communication, all make for great experiences.
Personally I wish all girls would receive vibrators for a birthday present at the age of entering puberty. They then can learn about their bodies. Have sex safely without fear of pregnancy or stds. Are more able to resist the advances of the overly testosterone surges of the male sex. It is easier to resist when one is not horny, to put it bluntly.
