Something is wrong with my erection quality

I have been having trouble getting hard lately. I didn’t have a problem but the last couple of days I have been having a real problem with my new g/f. I can get like half-way hard and then nothing. I try for like 20 mins and still nothing. Just blank. It’s not that it’s totally blank because I do get hard somewhat and I still get hard if I watch porn or am in the mood. So I am wondering what gives? This really sucks because I am 22 and really want to get some help.

Does anyone know of anything I can try? I’d like recommendations for stuff both short-term and long-term. Thanks for your help in advance

Start edging also don’t ejaculate while watching porn (but don’t stop watching and jerking off to porn). By the time you start fooling around with your old lady you’ll have so much pent-up frustration you’ll be struggling not to have hard ons.
