Bath towels

Moved back home with my family to both purse a degree and also help my parents with care because they need help at the time. My parents have always been strange however the other day they got undermy skin . Before work and after work I often shower because my job requires me to be very close to people I try really hard not to smell bad . I am one of those people who naturally stinks very quickly despite very good personal hygiene. I like large bath towels over the years I have purchased many of them I have about 10 . I hang them up to dry however many times I don't feel comfortable reusing them. I then use them to soak up any water that may have gotten on the floor. Then I wash and dry them with hot water and mid heat. My parents are now demanding that I use smaller towels the size of children towels to be clear I am nearly 6 foot tall . I am frustrated for multiple reasons but I am trying to be respectful. I am 6months from moving out. They also do not want to purchase them. I am frustrated because I don't like there towels and think they are gross. I understand the extra costs so I try to wash them with my clothes. It's just frustrating . I also am on a tight budget because although I am almost done with my degree. I don't start my new job until January. I feel this Is petty and am over them
