contraceptive coil and threads

[kitpuss]

I'm not really sure where to put this message but I'll try it here and see if I get any response.
I had a copper coil fitted 4 days ago. Apparently the threads inside can feel quite hard at first but then they soften. I'm a bit concerned about having sex for the first time, don't want to do it too soon if it is going to hurt DH, but am not sure how long to wait for them to soften.
DH is quite unsure at the minute, is worried that just feeling the threads will spoil sex, I'm worried that if they feel hard he'll be badgering me to get it taken out before we've given it a chance!
Has anyone been through this and has any advice?

I've had a coil in for 7.5 years (bar pregnancies) and had new ones re-inserted 3 times. DH has never said anything about it.

Can you feel the wires? I could feel mine easily (which is another story) but they were more like nylon fishing wire than actual wire if that makes sense.
