<human>: Can you give me the gist of the text in a nutshell?

My boyfriend [25M] and I [23F] have been together for just over 2.5 years. 

Our relationship has always been sexless, we have had sex only 3 times and all three times didn't seem to 'work' something on his end always went wrong. He thinks that always having sex will take away the appeal of it all. 

However.. He never does anything to initiate, and if he does.. I end up doing all the work. He has never once touched me. He even seems nervous to hold my hand in public..let alone touch me in the bedroom. I try and turn him on by dressing up, or doing things for him I know he likes..it always ends with nothing. 

I have talked to him about my feelings on our sex life, but I get a quick and snappy reply and refuses to answer any questions no matter what tone I ask them in. This makes me feel like it's me and that he is not attracted to me at all even though he says he loves, and he is not the type to just say that. 

Its kind of crushing my self esteem and my body image. How can I get him to open up and relax while talking about it? I have done everything I can think of to make him comfortable. 

This might be the end for me if we cannot figure out what is wrong. And it breaks my heart to even think like that. Please help me see a positive side.
<bot>: a 2.5 year relationship with no sex/intimate moments and I'm at a loss as to what to do.
