Disability and Incest

I am a person with a disability, I'm in a wheelchair, my accident was when I was twenty years old, my wife saw that I would be in a wheelchair for life and abandoned me, taking my two daughters who were small at the time, but it didn't bother me, I suffered a little from the distance with my daughters but I had to keep going without them at least for that moment, my parents took care of me, as obviously they had to do everything, my dad worked every week and I stayed home with my mom who helped me with everything, years after my accident I got used to being in a wheelchair, I bought a computer and from watching so much porn I found pages of incest and there I discovered what that kind of topic was, but it didn't leave me indifferent because at least modestly I had been sharing with my mom outings, small walks, restaurants, and obviously everything she made me do like a little boy, and obviously seeing all the dedication of my mom to me made me feel passionate and desirous for her since I also hadn't had sex or seen a naked woman in a long time, obviously my mom never found that on my computer, my mom was 46 years old at the time and I was 30 already spent ten years in a wheelchair, and I already had a different attitude towards life and disability, but my mind invaded by that topic and with a normal mom who was still quite sexual, my dad was a mason and worked in towns and left for weeks and I stayed alone with my mom the loneliness of both united us a lot, we always ate together, slept together, went out together and I with desire for her, however when I bathed my penis was always erect and on one of those occasions I told her that erection was due to desire for her and she said it was impossible and couldn't be, and there itself she I said I was in love with her and that I wanted us to be a couple secretly from everyone, obviously she got angry and didn't say anything, I then went out on the street after fixing myself up and didn't come back and later at night when she saw I wasn't coming back she started calling me and I told her not to come home if she didn't accept being my girlfriend...
