IUD side effect?

Rachel
I have the Liberte copper IUD (Canadian brand) and I had it inserted on Feb 29. I've noticed that now when my boyfriend and I go to have sex there isn't enough lubrication anymore and he has a hard time getting in ..🙈 we didn't used to have this problem. So I was just wondering if anyone else has had this problem and if it went away on its own...
Thanks :)
