Akward sex??

So had a baby 6 wks ago and was told to wait so I didn't have sex at all for the 6 wks. We tried last night and holy moses it was so awkward like my body's shaped different without a beach ball, I think he gained some weight but it used to be so effortless like we fit and now we don't. Its really sad actually. Has anyone else experienced this and does it get better?
