I am 16 and rarely get morning erections. i have a girlfriend and when i am intimate with her i often get hard but when i read up on morning erections i read that not geting them could be an issue. i'd appreciate any response thank you?

As long as you have erection with sexual arousal, you are fine. Morning erection or morning wood is a proof that you have appropriate erection but it's not always or often present in all men.

Morning erections are not necessary for a normal seual life and erections. They can occur on a full bladder, not having sex for a while etc. . It is not an issue and dont worry about it.
