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?

She tightened her muscles purposefully. Called a kegel. All women (and men) are capable of them.

Comments here saying she orgasmed- some seem to think vaginal contractions must mean a woman has orgasmed. Untrue. As you can tell by her comment afterwards and the timing women can simply tighten their muscles anytime, same as any other exercise.

Not everyone can, especially not that strong. Example 1: me. I can't do kegels at all, I've tried everything, practiced, used those "kegel balls", read articles and how to's, etc.

But when I have an orgasm my vagina literally squeezes and pulsates so intensely that it's hard to believe. You can both see it from outside and feel it obviously. My husband loves it when I squeeze his penis to death 🥰 So the muscles are there, I just don't have any control over them 😅

And no, my inability to do kegels hasn't had any impact on my life or health. I've given birth twice no problem, and I've never had issues with incontinence, or sex obviously.

Yep! That’s how I first activated my mind-muscle connection with my pelvic floor. I would practice starting and stopping while peeing, and getting control over the force of the stream. And once I knew what that felt like, I could do it in the bedroom. I would go in with an empty bladder, but I would consciously flex the muscles like I was holding pee in, or pushing it out, and it was….very effective on my partner, to say the least lmao.
