Am i the only one going thru this? 😕

My husband almost never initiates sex with me. I’m always the one who has to ask. Is it me? I feel bad for asking because his work schedule is so hectic but it just seems like he’s always tired. He’s not cheating or anything, he’s an amazing man who is faithful. But when it comes to sex its almost never a thing anymore 😕. He’s in the US Military btw.
