What did my partner just do?

[u/OkTough6333]

So yesterday me (M22) & my gf (F21) were having sex. usually when we do it, we routinely do it in the missionary position and i usually finish and she’s able to have a good time too, but yesterday something unusual happened. As I was thrusting, I was having difficulty finishing – which is not common, since I usually am able to finish with no problem; but yesterday it just wasn’t clicking for some reason and I was thrusting for like 10-15 minutes. Then as I was continuing thrusting, all of a sudden I feel an enormous heavy pressure on my penis – the feeling was so heavy that, it was as if my Penis was being squeezed from all sides. With this enormous pressure on me I was finally at last able to finish & it was one of the best feelings ever. I looked over at my gf and I asked her what the hell just happened? & she just laughed and said “magic”

I’m still confused on what happened even after a day just passed since. Because we've been doing missionary for so long and nothing like this has ever happened. What do you guys think?

Two possibilities:

Kegel muscles. She tightened them. It’s something us women can do, and we can work on them too. It’s actually good for us to do that as we age and after having babies to help with other things.

Or she orgasmed, it can tighten things when orgasming too. More of a reflex.

I took her reaction to mean that she did it intentionally so my guess is… kegel.

Yes, but is it also possible to relax the muscles? Because OP wrote he usually doesn't have a hard time finishing, but this time he couldn't so easily.

This sounds like she tightened them. But yes, it’s also easy to relax them. I can push and pull with them. It’s the same muscles used in peeing - holding or stopping urinating is the pulling, and sometimes when trying to force myself to pee (like I know it’s going to be awhile before I get to a bathroom), I push down. Same muscles. I get a lot of practice outside sex, I imagine most women do.

Now you absolutely can work the muscles to tighten even more and do impressive things, but the very basic squeeze function isn’t that difficult and something most of us do outside the bedroom almost every day. Depends on how tight she squeezed him, but even working them isn’t that hard. I can sit at work and squeeze and release my kegals without anyone knowing and a lot of women just work on them like that. It’s only a few minutes a day. It can help with aging related or pregnancy related issues that cause accidentally peeing ourselves as we get older so a lot of us are aware and work on them. It’s not a huge secret.

It took my gf years to learn how to unclench them, she has kegels of steel and would crush my dick until it was sore and soft and spongy and couldn't get hard again. The closer she got to orgasm, the tighter it would get, like fighting against knots of muscle.
