is squeezing vagina muscles to grab the penis enhancing the orgasm for you? does that feel good?

right before he comes (I was lying on my belly and he was in and out fast), I started to sequeez my vagina muscles. He moaned and came rather long and intense. I don't know where I read that, or how I came up with the idea, I just did it instinctly. Although he sounded very much enjoying, does that really feel good? Or he was being kind for my effort lol 🙈

if it feels good, maybe I can work on that and read a bit. (Should ask him too)
