Healing through a relationship

It's been 60 days since I started my NoFap journey. At this stage in my recovery Ive noticed some real significant changes in my mind. For one my anxiety has gone way down and my confidence has increased. I don't really have the urge to watch porn. when the thought pops in my had to do so I just easily deny it and it goes away just as quickly. I can go without masturbating and not really feel like I'm torturing myself. However I don't think that my body has made a full recovery yet.
In the past couple weeks me and my boyfriend have become very close. We have come to the point in our relationship where I felt comfortable enough to tell him about my nofap. He is more than amazed with my self control and actually proud and supportive of me which has lifted a lot of anxiety off of my shoulders. I have made the decision to only have any type of sexual gratification when were together. Which actually seems to help with me keeping my mind off of porn. Our sexual preferences work great for each other and I don't have the issues when were together that I used to. But because we are both guys I can see and physically feel the difference between my body that is recovering and his healthy body. My boyfriends erections are solid to the point where I can't even move it sometimes and they last well after orgasms. My erections are there but if I had to compare them I would say Im at 75 sometimes 80 and they only last while I'm aroused. its easier for him to reach orgasms and sometimes I takes me a while to get close which frustrates me. At other times I just know my body just doesn't want to orgasm. It doesn't discourage me as much as it frustrates me. My boyfriend understand and he hasn't expressed any discomfort about my body or my penis and how it operates. For him I just respond to sex in different way but for me I only desire for my body to operate normally like his does. He's told me about how he has random erections and sometimes wet dreams, as well as being able to masturbate throughout the week and still be able to hold a solid erection when were together. I can go a week without masturbating and still need coaxing for a full blown erection it frustrating. It's like I can see what my body is supposed to do but it doesn't. It feels like I'm just waiting for my body to work right. ​
