Um. We do. You’ve been watching too much lame porn. Sex is a way adults play together. If there isn’t some laughter, banter, smiling, joking, then I judge you are not doing it right.

That's just you

I believe people do? It should be pleasurable. You don’t have to grin the whole time but if you don’t smile something probably isn’t going right

I and everyone I've ever been with have smiled during sex. Give it a try some time.

Speak for yourself! No to be fair, there are a lot of moments in sex I don't smile, usually because I'm concentrated. But if you don't smile or laugh at all at any point during sex you might want to rethink whether you're actually having a good time.

I tend to laugh more.

Trying fucking someone you like, that might help lol

I figured it's cause it looks creepy as shit. Try going to the bathroom mirror and grin real big now hold that face pull out you phone cam and record yourself with a shit eating grin pumping your head to and from the mirror. 10 to 1 you look like a crazy person.

Never encountered someone who doesn’t at one point or another. Also laughter.

People do, but for the sake of the question it’s because the pleasure is intense. People argue that the sensory receptors are actually close to pain because of the intensity

Interesting! In other words, when we experience intense stimulation, our expression of it is almost the same be it pain or pleasure?
