Similar to above, but the whole "tightness" "looseness" thing being associated with promiscuity and crap like that.
I am, in fact, perhaps my tightest after orgasming. It has further incentivised my boo to lick my pussy until I cum before penetrating me once. I love it, because I'll be even more sensitive and FEEL tighter too, which of course makes everything else feel bigger and even more filling than it was already. And even when he gets me off before sex, he still prefers me to cum during or just before he does during penetration anyway, so there's no trade off. And really, who doesn't like more orgasms?
Additionally, I also have the most sexual experience out of everyone he's been with, and he had often said things about my tightness during sex and when I inquired about whether it was a me thing or a general thing, he said "no, I really didn't know they could even be that tight." in a good way. neways.
In conclusion, pussy myths in general are usually pretty fn stupid.
