iud strings? fingering ?

Daisy
Hi I got my iud a week ago exactly and today I checked up there for the first time and was able to find my strings almost immediately and that freaked me out ! Will my boyfriend ever be able to finger me without feeling them? that's so scary ! I'm sorry for being dramatic and also should I ask my doctor to cut them shorter on my two week check up? someone please help! will sex hurt after the iud ???
