I don't know what to do anymore

I love my boyfriend, but we have a real problem in the bedroom...or lack of bedroom I suppose. we have been dating for a year and a half now and recently moved in with each other 6 months ago. At first we decided to wait to have sex until we moved in together which was fine. Now that we have moved in I can count the number of times we had sex on 1 hand. Previously he have been in long distance a long distance relationship for 5 years so he says he just got use to not having sex anymore because of that and his sex drive is low. I went through his internet history (I know that's a big no no lol) and discovered that's not it. when I talked to him about it he said he just has to get use to having sex again. I'm trying to be supportive, but meanwhile it's killing my self esteem. other guys want to have sex with me, but my own bf doesn't. at this point of time I just need advice on how to handle this or if anyone else is going through this. I love him to death and everything else in our relationship is going fine except sex.
