I swear I meant to answer this!
For me, I am definitely drier than I was pre-T. Especially once my period stopped. I've also found in a sexual context that it takes a lot longer for me to get wet. There was also a really noticeable difference for me after my hysto. It's not painful or anything, and as far as my experience goes, it hasn't caused any other issues.
(PS: I'm curious about these hygienic sponges? I don't think I've ever seen or heard of them. Are they like tampons? If you're not too dysphoric about reaching around down there, I have a friend who is on the small side and they swear by those menstrual cups. They're washable/reusable so it may actually be a good option to consider while you're waiting on shark week to end and to have around just in case.)
