Help! Husband won't have sex!

I've now been married over a year and my husband has still not had sex with me. Before we were married, the last time we had sex was one time within the year before. That's it. There was also a period of 3 years that we didn't have sex. Now, it has been so long and I constantly think it must be me, but I am super self conscious and scared to just take the control and just try mounting him. My husband loves me and he has never cheated. I know that. But he never talks about it, if I bring it up, he gets instantly nasty and walks away from me or tell me to shut up.

WHAT DO I DO? I NEED LOVE! Your own fingers can only do so much in desperate times. I want my husband.

PS it is also not easy to just mount and do him. He has quite a large cock and when we used to have sex, we always had to ease into it like I was a virgin every single time. Forget doing it 2 days in a row too.
