I know how you feel, I have had the exact same thing. After my ex I started renting with 3 personal friends. I still had the urges you had and couldn't stop myself ordering some.
I had to hide it all the time, worry about them finding out, but they never did (apart from one of them who already knew, he is a very close friend mind you)
I have worn them in public and around friends any family too (under clothing ofc), but most people would never second glance you, if they did its probably someone who has the same thing as yourself!
Enjoy it I wish I had the freedom to wear them as and when and as freely as I wanted!
