You've been with him for about a year, I'm sure he wont care what you look like with your clothes off

It usually the things us girls worry about that they dont notice!
Like...stretch marks. the inside of my thighs are riddled with them! the back of my knees too, it wasn't until one day I made a comment about them he went 'What are stretch marks? :S'
And Ive got cellulite on my bum, he thinks its the cutest thing he's ever seen...he's even named his favorite dimple...yeah,..i know! haha
but honestly, if you make a big deal out of it then so will he and that's when your self confidence hits rock bottom! If you just get on with being naked it'll just come as a natural thing
(self experience)
As long as your relaxed when it comes to sex you'll be fine, make sure he stops if you need him to, take it slow, it'll hurt a bit (or maybe not at all) and feel a little uncomfortable at first but...thats the same as wearing in a new pair of shoes
