Is it a good thing that I got rock hard erections from something else? (no porn)

I got my rock hard erections from something else. We don't have to depend on porn and masturbation to receive erections.

 

Well, like I remember my parents adopt a new dog and sniffing on me when I went to their house for a visit. Also, when I was a teenager, one time my mama was sniffing my feet to make sure they wasn't stink. I also kind of fantasize my mama's soles of feet because of her plump and meaty size. Her feet sometimes propped up on a table showing her soles. She's my mama and I'm supposed to love her. I also watched you tube videos about bears. Is it a good thing?
