My girlfriend says she can live without sex, this of course for a man is very concerning. She said my overweight is a problem it doesnt let her breath when I am on top therefor it makes the whole experience very uncomftable. The because I am overweight she said that my size has diminsh and doesnt feel much anymore.

I though always it wasnt about the size but how you used it. I guess I was wrong.... Any recommendations? should I give up on the relationship?

Can the relationship survive without sex? She still talks to her ex, can this be a problem? maybe she is saving him for later in life?

She has repeadetly told me she loves me and is with me and she wouldnt be with me if she didnt want too. Also, she said no matter what happens she will never go back to her ex.

What can I do? Is it over?
