IUD question I would like answered

Jordan
So I just got my skyla inserted on Tuesday and my doctor rushed me out of the office so I wasn't able to ask her much so my questions are:
1. If I got it on Tuesday and today is Saturday how many days do I have to wait for the skyla to go into effect so I can have unprotected sex and if he "you know" inside of me will it be ok "we haven't had unprotected sex yet that's y I'm asking"
2. When am I able to start going swimming in the pool or take a bath
3.  Will my boyfriend be able to feel the string inside of me 
4. As weird as it sounds can I i guess pleasure myself and if I do will my IUD thing move 
Thanks for your time and please answer the questions lol
