Would anyone have an answer? Or who I could go see who could help me.

Can you get an erection by yourself or can you not get one at all?

If you can't get one at all, it could be either of those things or something else. You should see your regular doctor and get a physical. You could also see a Urologist, but your primary care doctor should fine for a first-step.

However, if you can get an erection by yourself, but not with your girlfriend, then it's probably anxiety. That will have to be something you have to work through. Realize that she's with you, not with any other guy. So there must be something special about you that makes her want to be with you, even if you aren't experienced. Maybe she likes the fact that you haven't been with a ton of girls. If you are worried about pleasing her, just ask her what she likes. And remember that a relationship isn't all about sex. Focus on friendship, getting to know her, and letting her get to know you. That's important, as well.

Yea I try and masturbate by myself and all I can get is a semi hard erection, not a full one if that makes sense. But while I am masturbating i cant do anything but think that something is wrong with me and stuff. So I think its a mindset but I am not completely sure.

I still wake up with a morning erection if that helps at all.

I think you should try to work on the anxiety. If you can get an erection when your mind isn't involved as much, that's pretty telling. It can also take time to get fully comfortable with another person in such an intimate way.

It could also be that you rushed into the sexual part before you really got to know each other. I don't know, that's your call. But just because you're a guy doesn't mean you have to jump into bed just because the girl is ready. And just because your body's ready, doesn't mean your mind is. You can slow things down. Say you want to get to know her more and really establish a bond before you re-take it to the next level.

If you think you're ready and are just too hung up on her previous relationships, you need to stop thinking about it, especially in the moment. And I do also hope that you are using protection, since she has had more experience.

Yea we have only been going out for about 2 weeks. I told her things were moving to fast and I needed to slow it down. So I am waiting a week til I see if I can get an erection in any way(ie: masturbating or with my girl). Just gunna step back and let things slow. Thank you for your help.
