Help me decide how much I can do with my GF

Hey guys! I'm approaching my 1 month mark of no PMO and am excited. I think its safe to say that i have flatlined starting around the 2-3 week mark. My brain went into a blank, i felt like i dont even know how to socialize, didnt feel like i had any libido, emotionally i just felt numb and indifferent, etc. Would you guys say I probably flatlined there? Slowly but surely ive felt more like normal but not quite.

Back when my girlfriend still gave me handjobs/blowjobs, she could get me about 70% hard, maybe 80% on a good day. but i could never get any harder and she could never make me cum.

We tried to have sex a year ago back before she knew about my PMO and i wasnt able to get it up. I think a little bit of it was just my brain on porn.

Other info: Ive been consistently getting streaks of increasing measure, around 10-25 days and felt increasingly confident on each try. My porn habits before I started hitting these streaks were watching porn usually every 1 or 2 days (maybe PMO twice a day about 20% of the time). I dont watch any crazy stuff. Just straight up one on one Brazzers type stuff.

with these things considered. how intimate can i start getting again with my girlfriend? Cunnilingus at least? Full on sex? Please help me get a lot of collective answers. Ive had trouble getting lots of replies on my threads. Thanks!
