Is it normal to suck your own dick and swallow your cum

I don't remember the fist time I sucked my own dick but it was several years later when I had my first orgasm. I think I was around twelve when I was sucking away when it started feeling so damn good then I came with no place to spit I swallowed it. For weeks I did not do it again because I thought I was going to die. One of the boys was on the school play ground telling about a girl sucked him off and swallowed it all. He said she made the comment it makes my skin shine when I swallow cum and besides I like the taste. They all laughed, one kid said wonder if you eat your own cum would your skin shine too! It was time to return to our classes but I could not wait to get home, get in my favorite chair and suck my dick this time I tasted it really good before I swallowed it. I agreed it tasted bitter. But I liked it. for several years I would give myself a hummer when I could and sometimes just jack off. What I would like to know how many boys that have tried but couldn't and how many did. When I sit in a chair with my butt up on the edge my dick stands at the right angle so I can get it in my mouth to the back of my teeth with no problems. If I force myself by pulling on the rung of the chair when I cum it goes right into my throat and all I feel is the hot fluid cumming and going. I wonder if everybody has hot cum when they cum. The girl I am dating now does not know I can suck it better than her but I am teaching her where the right spots are. She got me to eating bananas almost every day and some pineapple at lunch and it has gotten sweeter tasting. She just don't know I know how sweet it is. Should I tell her about my little secret or keep my mouth around my dick.
