Advice please ladies

So I am 24 and my husband is 28. We just got married a few weeks ago but this issue has been going on a while. We have an amazing relationship outside of him NEVER wanting to have sex. He always tells me he’s to tired or not in the mood even when I’m rubbing up on him. It’s so absolutely depressing. Then when we do have sex which is about once a week if that. I always initiate it, he never touches me it goes blow job then sex every single time and the sex lasts 2 minutes if that. I am so discouraged about this and have no idea what to do. Each time I bring it up he gets really defensive. Also he’s not cheating, I can assure that much.

Any advice and please no rude comments!

Thank you 💕
