My dad is making me feel uncomfortable
Im 13 years old, and my dad is 58. i have 2 siblings one is 15 and my other one is 25, my dad makes me feel uncomfortable always when he is around. he nibbles on my ear randomly, and he smacks my ass alot but i always thought of it as a joke, but now he keeps on doing it. one time i was sleeping with my mom and dad i was between of them, and i was awake, it was like 12 oclock. he randomly got up and kissed my lips and left the room, i still remeber that momment i was so confused, the next day he told me he just went to my brothers room to sleep. he also tells me come sit on his lap regularly, he comes into my room and randomy nuzzles his face on mine kissing random spots. he also bits my feet and scratches it, but he does it to my other siblings too, but mostly mine so i always thought it was normal. I dont know if im being dramatic, so could you guys please give your guys opinion on this?
