Erection Angle and ED

[Uberman]

Hi guys, getting straight into it attached is how my dick looks fully erect:

It's curved slightly downwards at max erection and it parallel to the floor. This causes issues while trying to penetrate my girlfriend.
Also, I can only reach complete erection when I really squeeze my PC muscles, is this normal as well? As soon as I let go of my PC muscles I lose my erection, and I can't keep my muscles squeezed at full effort for more then 10-15 seconds max.

Edit: A few extra notes. I can get erection easier while I'm sitting/ sleeping. As soon as I stand up I lose my erection, also my heart starts beating really hard.
I'm a completely healthy young man, I workout often, eat well, and have a low body fat percentage. Also my test levels are normal

How do I got about fixing my problems? Thank you
