Ladies, What are your experiences with the coil / IUD (non-hormonal)

I am booked in to get my implanon hormonal implant in my arm removed at the end of June and have the non-hormonal coil fitted. I have had enough of hormones, being on the pill since the age of 16 (I am now 23) then getting the implant 2 and a half years ago. I am due to go travelling later this year and so have to have my implant out early as I would otherwise be having to get it taken out mid travelling probably somewhere in Africa so that is not a good idea. I do not want to get another implant and really just want to be myself and be off hormones for a while.
What are your experiences with the coil?
Did it hurt having it put in and taken out?
How long before you could have sex after having it fitted?
How much of a risk is there really in causing permanent damage to the uterus? My nurse just said ”“touch wood” I have never experienced this happen to anyone” jokingly (reassuring…)
How would you compare this to your experiences with other forms of birth control bearing in mind my partner really prefer not to have to use condoms now that we have been tested and are
clean.

Note: I know all about the fact that it does not cover me for STI risk, my partner and I are in a monogamous relationship and STI testing is free in the UK and I get tested with any new partners. This is about side effects and personal experience please!
