First time sex after pregnancy

I had sex for the first time since I've been pregnant (husband just came back from deployment) and it was explosive! I mean we've always had good sex but this left me tingling all the way down to my fingertips and unable to move for a good five minutes. Is this what I've been missing this whole time?? I felt like my g spot was way more accessible if that makes any sense. Is that possible? Haha. I'm 12 weeks 4 days
