Sex with mirena..

So I've had my iud in for a week and been cramping since getting it in.. I honestly don't like the thought of something other than an unborn baby chilling in my uterus. Anyways I've also been extremely horny since getting it in and me and my fiance finally had sex last night since getting it in. I was extremely sensitive..like he didn't even get half way in and I started to moan and wanted to scream (in a good way)... I still live with my parents and have to be quiet when we do anything because my dad doesn't want us having sex in the house but last night was basically impossible for me to stay quiet. It was amazing..it always is but it seems like this birth control is making me extremely sensitive and when I'm horny I feel like ripping my fiance apart. Last night I was biting him, pulling his hair, basically acting like I don't usually act during sex. Has anyone else experienced this with iuds..?
