Any Advice to help obtain fuller erections

I’m pretty happy with my size, over 7” fully erect. That is the problem, I have trouble becoming fully erect. I get “morning wood” alot and it’s always rock hard, and on occasion if I’m really horny I get a full hard penis, but more often than not it’s 75-85%ish. What can I do to help get to 100% more often?

Kegels!
