Makes me incredibly self conscious...

I was reading on Instagram a post and the comments and it was about how during sex when a girl does that tightening thing around the guy’s 🍆, it is almost an instant cum for the guy, and there was a lot of guys who agreed in the comments...and my boyfriend had told me before that his friends and him were talking about it and when their girlfriends do it to them and they also all said that it makes them cum almost instantly...I’ve tried it on my boyfriend before, like even before he ever talked to his friends about it, and he said it felt “weird” bc we had just been laying there and I did it, and he goes “wait do that again” and I did it and he goes “that feels weird but cool at the same time” but it didn’t seem like it felt good for him...I’ve even done it during sex, and it doesn’t have an affect on him at all...so it makes me incredibly self conscious, does that mean that I’m “loose” down there? Him and I have had a lot of sex over the year and 7 months we’ve been together, like sex almost every day or every other day, and several times a day every time, and he’s well endowed I’d say, he’s about 8 inches...so could the having sex so much have made me “looser”..? Idk, I’m just really self conscious about it because for other boyfriends, it makes them cum quick, but with mine, it doesn’t seem like it affects him at all..
