Thoughts on Menstrual discs?

So I’ve been using tampons for the past 10 years and I was tired of having to change my tampon 5 times a day and saw that a disc can last 12 hours so I was intrigued. PLUS you can have sex with one in!! So I wanna know how well they work for you & if you can actually have sex with one in without feeling it and without the mess.
