What does it feel like for a man if a woman tightens her vaginal muscles during sex?

I can’t really think of a better way to put my question lol. Here’s the deal, I’m kind of self conscious about whether I’m “tight enough†down there. It’s not a huge issue, my man still cums and has never said anything about it but I’m aware I’m not as tight as some women are. So it’s kind of become habit for me to tighten my muscles during sex. Sometimes on purpose and sometimes I just tense up. It didn’t occur to me until last night that it might not feel good to men? Or he might know exactly what I’m doing and know that I’m clearly self conscious about this.
So, can you tell when your partner is tensing up during sex? Do you like it, or does it help tightness at all on your end?

EDIT: you know what, I’m so proud of how everyone has treated me and eachother in this thread. I expected some hate and nastiness but everyone has just been nice and supportive and helpful. Thank you all. Now I’m horny af and miss my mans. Maybe y’all are horny as **** as well and that’s why everyone’s being nice
