Hi Bitesize,
I definitely agree with mlrchi, if you don’t have the glass dilators you should definitely purchase them! Also, another helpful thing (if you aren’t doing it yet) would be to practice inserting the dilators while standing that way you could easily put them in in the bathroom of your shared place. For me, I have had success if I put one foot up (usually my right) a little higher – you could probably use a bathtub, or even the toilet. I kind of “squat” a little with my one leg up and that has been a pretty easy way for me to put them in while standing. Who knows, you may already be doing that. 🙂 But I definitely agree, the glass ones would be worth getting. Also, and this is totally dependent on your comfort level of course — you could talk to your roommates and explain your situation, and I’m sure they would be willing to give you some privacy. But again, that is totally up to you and if you are comfortable with that. I have talked to many people about it and everyone I’ve talked to has been kind and supportive.
Anyways, I hope this was helpful! Hope you have an awesome summer here in the U.S! 🙂
