I've been a Nuvaring user for like a decade now, but for some reason, I was still nervous about trying this.
I finally decided to take it for a spin one night when my period was still winding down but I anticipated getting some action, and WOW - pretty impressed. The mechanics were exactly the same as inserting the NuvaRing and made for blood-free (if a little dry without some handy lube) sex. Taking it out was just as easy for me, although EVERY BODY IS DIFFERENT and if the thought of probing around in your vag freaks you out, it's simply not gonna be a great time for you. I'm giving 4/5 stars because it is inevitably a messy job getting it out... and I'm not thrilled by the thought of another single-use plastic period product but I know flex is making up for that with their other items.
I have not yet tried to go all day using this, but tbh I find it easier to use than the cup and as a device used to hold back the red tide as you get your freak on, I give it a thumbs up!
Also, to all the fuming women writing bad reviews after being reminded of the existence of sex... please return to your convent and find something more productive to do. Thank you.
