Advice: Do I tell him I'm not attracted?

I currently am dating a friend’s brother who is a complete sweetheart. Here's the problem: I am not attracted to him. We have been together for three months and only had sex twice, and both times I have not enjoyed it. He's on the heavy side, has tattoos, both nipples pierced, etc., and I know it’s all physical, but emotionally I am not into him either. He works in the freezer in a food store (he is 29, hates school, but after meeting me he wants to better himself within the store) while I work at an accounting firm and have goals. What I am trying to say is, what do I do to let him know that I would just rather be friends without saying, "I am not physically attracted to you nor do I see a future with you, aka it's not you, it's me?”--It’s Me
