I need advice or something.

I seriously cant take it. It may not seem like a big deal but my boyfriend literally has no sex drive. I do not make him have sex with me if he doesnt want to. I usually just deal with it. But I do try sometimes to get him going but if it doesnt work then so be it. It's been about, almost a month since we've been intimate. I've asked him before if hes depressed, if he is just not into it anymore and he says it's nothing like that and yes he still is in love with me. (Thank God.) Today he made the comment after I made the joke after my dog was kissing his face I joked and said, you let the dog kiss you but you act like its work to kiss me. And he said BECAUSE I HAVE TO KISS BACK AND ITS TO MUCH WORK! Everything I talk about is to much work. I feel I may be over reacting but I'm struggling here. I would never cheat or do anything to hurt him because I live him. I'm head over heels for this guy. We've been dating almost a year and a half. It's just so hard to try and be satisfied sexually when he NEVER wants to do anything. And no hes not cheating. And yes I'm sure. I just need advice or just see if other women go through with this to because it's frustrating.
