Fulfilling sex, but having issues with myself

I’m having a hard time getting erect, and when I do it seems to go away quickly. I am in a new relationship, and sec is still generally very good with hand/ oral stuff but it’s been really frustrating for me as whenever we try to move on to penetrative my body is like nope! She still seems to really enjoy herself, and I really enjoy time with her, it’s just so frustrating to not experience the rest


How often do you watch porn? Do you know what the cause of your Ed is?
