After 30 days, how to know if its still working?

So I've been just over 30 days of no PMO.  I believe I have been in a flatline for the whole time but I kind of want to know if there's anything physically wrong with it.  I can't get an erection from just playing with it, so I have not jerked off for the whole 30 days.  But I kind of want to just to know if it still work, and whenever I be cuddling with my gf or messing around with her (no penetrative sex yet, kind of afraid to try) I feel like I'm gonna nut just because its been so long since I have.  Is this normal.  That's why I kind of want to masturbate just to relieve the pressure but I can't get hard.  Should I try and masturbate (without porn of course)?  I've been getting morning wood but it hasn't been overly strong or as large as I remember.  like I feel a lot of blood going to the head where its enlarged and crazy sensitive.  Is this normal or could it be a sign of something else.  So my questions are, should I try jerking off so it won't feel like its about to blow whenever I'm cuddling with my gf or whatever, and is everything I have described normal to a flatline? 

Everything will work OK when you're healed. In the past I've masturbated to check if everything worked during my flatline and every time it has lead to a relapse. So, my advice it to stay calm. You're not permanently broken. When you brain has rebalanced itself sufficiently, everything will start resetting to normal.

Don't worry about oversensitivity either. When I've rebooted in the past, penetrative sex made me cum almost immediately, but it settles down again after a few attempts. Your doing the right thing. Just be patient.

I would try not to obsess too much over if youre "cured" or not. The very fact that youre asking this might suggest that you need a little more time to recover. Its when you dont even think about it and you just suddenly know, then Id say youre on your way to cured.
