IUD and sex with your significant other

Sammi
I'm in a LDR with my boyfriend of almost 2 years. He left for med school in August and I'm going up to see him for thanksgiving week. It will be the first time we have sex since July and the first time since I had the IUD inserted in August. I just want to know how yalls boyfriends feel when y'all have sex or if it hurts them. 
Cause since this is going to be the first time in forever that we'll be intimate, I want it to be great for both of us.
