Any advice would help so much

I’m trying to make this as short as I can. Please help me cuz I’m so lost In life with this it’s taking over my life. As I got older (28) I realized sex was all wrong. I just use to do it cuz it’s what seemed us as humans were supposed to do but I’ve never actually been turned on with someone and never had an orgasm with them and I can’t stay focused during the moment so am I broken or is this more of a mental problem and is there hope? I’m so stressed and down and I feel so lost that I’m missing out. I can orgasm myself just not with someone no matter how much stimulation or whatever. I can’t even get in the mood. What is wrong with me please help 😩
