I always feel uncomfortable around my dad?

Well I'm 17 and SOMETIMES I catch my dad looking at my chest or staring for too long... and lately he's been making me uncomfortable whenever I wear shorts or tank tops (I don't know why) it hasn't always been awkwardish between us. The other day he poked my thigh in the car and asked if there was a bruise just so he could look ( there clearly was no bruise)... I feel like he makes excuses so he can look at my legs. it makes me feel uncomfortable. It's hot outside And I feel uncomfortable just to wear a bathing suit or shorts in front my dad... My dad loves me a lot I know he'd never do anything !! I live alone with my dad ,,,, Just want to know opinions if this is normal or not. Or if any girls feel the same way?
