Something happened to you and you have self-esteem issues. I know how it feels. Your boyfriend knows you're attractive, you know you're attractive, but only one of you is really believing what you say. You need to look at your past, see what you've overcome, and tell yourself that you're not what anyone else said you were, and even if you can't get over somethign that happened, reealize that you're a different person now; you said you had a crappy past, not that you have a crappy life; somethign has changed for the better, and you are bopth the cause and effect of that change, you just need to realize it.
I don't care if you are the single most beautiful person in the world, it just doesn't work that way. Trust me, I have a Y chromosome and I know how these things work.
The honeymoon is over. Fairytale romance only lasts for a little while, then you need effort from both sides to keep it going. This doesn't mean anything is wrong, but you don't have the thrill of it being a new thing anymore.

What you need to do is force yourself to overcome your inhibitions and make a move. Go out, ifnd a nice place t odo something romantic where you won't be interrupted or seen, and do something there. Some ideas: go hiking and make use of the picnic blanket, defile your elementary school playground, go to the beach and throw a blanket over a table (not one the sand, trust me,) figure out when the automatic sprinklers on the local golf course turn on at night and run around naked together, just be creative.
