Is it normal i can't stop cuming into my sister's food and shampoo

Help Me, absolutely true! There are lots of times I just see a shampoo container or face wash and can't stop myself, I jerk off fast and usually blow decent loads, it usually only takes a minute or less, often many times a day, into face wash tooth paste her thong panties, tampons, and now into her special milk and cereal, drinks like coffee, red bull, I cook most of her food because she is a lazy shit, so she eats at least half to a cup of to a full cup of jizz a day, she's 24 and I'm 19 so, not too creepy, she also changes clothes and gets naked in front of me, fully shaved! a beautiful pussy! She's worked at a gym for the last 4 and a half years, rock'in body, 10 out of 10!! I've literally seen a thin stringer of wet pussy pre-cum stick onto her thong from her pussy and slowly break sliding down her pussy and leg, she casually wiped it up, as she sat down on the couch next to me to take a bong hit, those 32C cups in the sunlight, fully naked, she said I'm gonna hop into the shower, coughs hard after the bong hit, contracting her tight stomach and bouncing her tremendous breasts, knowing I've already cum into every product she is about to rub into her body, her lube, her lip gloss and even her clean panties rubbing her twat, I start whipping up her dinner, I fuck the dough of her pizza, all day, probably 4-5 loads just in the dough of her personal pizza, maybe a cup if jizz, then when she is in the shower after that display she gave me, I pump out 2 more loads on the cheese layer, maybe another half cup, then to make it even better out of the back of the fridge, for days like this one, another 2 full cups of Cum in the sauce, measured out, the ranch sauce is 2 cups Cum instead of mayo! She loved it, she said it was a bit saucey, just the way I like her to have it, it's a problem though and here is why I need help, the doctor told her she has the testosterone level of a woman going through a sex change, what do I do? I'm addicted!
